There are cocktail bars and there is Cinco Lounge. This is Lisbon's premier cocktail venue, a real after-dark treat for aficionados of the mixed drink. Its intimate, semi-lit ambiance also makes it a wonderfully romantic place to enjoy a drink with a loved one. You can perch on one of the counter stools and chat with the bartender as he prepares your choice - and the menu lists a bewildering number of cocktails - or find a corner and sink into any one of the plush, marshmallow-soft couches hugging the walls. Even when it's full the bar oozes cozy charm. The soundtrack is smooth chill out but the music never overloads the ear or gatecrashes the conversation.
Recommended for Romantic Things to Do because: Over the last few years, cocktail bars have pooped up all over the city. Some have proved themselves admirably. But Cinco Lounge remains the standard-bearer.
Paul's expert tip: if you like a little umph! with your drink, order the "Nim Nom Atom Bomb", an explosive combination of gin, cointreau, lillet blanco, Pernod, lemon juice, lime juice, egg white, and a dash of gomme syrup.
Portugal's very own Disneyland palace crowns the highest peak of the Serra de Sintra mountain range and is one of the most distinguished landmarks in the region. The 19th-century wonder conjures up an image of a child's Lego-brick toy with its turrets and domes and colourful pastel facades. Indeed, it's a hotchpotch of different architectural styles. Commissioned by Queen Maria II for her husband Ferdinand Saxe-Coburg-Gotha, the multi-roomed palace is crammed full of rare and priceless antiques and curios collected from all over the world. Opulent furnishings are found throughout the salons, and the décor is especially lavish in the Ballroom. The Arab Room is another contender for the richest and most extravagant home decoration award. Enchanting and romantic in equal measure, this is a place to let the imagination run wild and live like royalty for a couple of hours.
Recommended for Romantic Things to Do because: Keep an eye on the weather. The mild micro-climate means that sometimes the palace is hidden by mist or low cloud.
Paul's expert tip: Photograph all you like outside but it's forbidden inside, even using smartphones.
Don't be put off by the rather incongruous location for despite being situated in the northern suburbs and approached by concrete housing blocks, this utterly romantic 18th-century royal palace stands alone as one of the grandest and most sumptuous in the land. Actually, it's one of the finest examples of Rococo architecture in Portugal and the interior hides a treasure trove of exquisite furniture and period décor. A highlight is the opulent Sala dos Embaixadores, built by Robillion and which featuring a stunning trompe l'oeil ceiling. The palace gardens, embellished with trickling fountains and trim topiary, are laid out in formal symmetry and provide a relaxing and highly enjoyable extension to the tour.
What better way to spend a romantic evening with someone you love than enjoying a candlelit dinner while listening to the haunting strains of fado. This is one of the most respected venues in the city, a fado house tucked away in the residential Lapa district known for its roll call of illustrious singers and guitarists. Expect first-class a la carte service - the restaurant upholds Portugal's rich, culinary traditions with a delicious choice of traditional dishes, and a list of carefully selected wines. The singing takes place between servings under dimmed light, the hushed audience serenaded with voice and guitar over the course of the evening.
Recommended for Romantic Things to Do because: Of all Lisbon's fado houses, Senhor Vinho is probably the most exclusive. It's, therefore, the choice of many locals seeking an authentic fado experience.
Paul's expert tip: Book a table in advance and check whether any tour groups are scheduled to visit. The atmosphere is far more intimate without the coach parties.
Whisk yourself back to the dapper days of the 1920s by stepping inside this veritable gem of a café. This is one of the finest examples of an early 20th-century Lisbon teahouse, and the bygone ambiance is absolutely beguiling. The building stands replete in original décor, all marble walls, decorative stained glass panels and custom-made counters filled with an amazing selection of cakes, sweets and all manner of homemade goodies. Busy waiters in smart waistcoats and bow ties hover around tables in quiet indifference - they've seen it all before, and their manner is sometimes brusque but always efficient. For the first-time visitor, this gleaming reminder of a gentler age is a wonderfully romantic and captivating experience.
Recommended for Romantic Things to Do because: Favoured by locals, many of whom dress for the occasion, this is café society at its most elegant.
Paul's expert tip: The specialty here is the hot chocolate, a rich dark concoction coifed with a dollop of whipped cream. Tempting at any time of the day.
To really experience Lisbon in a novel and romantic fashion, hop on board the number 28 tram. These bright yellow streetcars shake, rattle and roll their way over the city's most picturesque neighbourhoods to follow a meandering track past monuments, museums and miradouros (viewpoints). The tram connects Martim Moniz in the Baixa (downtown) district with Campo Ourique, an area west of the city centre. Along the way, the carriage trundles by under the shadow of landmarks like São Vicente de Fora in Alfama and the Sé (cathedral). Further on it snakes around Praça Luís de Camões in Chiado, one of the capital's prettiest squares, before hissing and creaking towards leafy Estrela, known for its church and landscaped gardens. And the best thing about the journey is that once you've reached the end of the line, you can do the same excursion in reverse.
The tearoom at the Palacete Chafariz D'El Rei exudes exceptional charm decorated as it is with original period furniture, which is an architectural signature evident throughout the hotel.

The unspoiled beauty of the Sintra coast lends itself to some incredible walks, and the trail that arrows its way through the Guincho-Cresima dunes is one of the most rewarding. The dune field lies within a protected reserve and is accessed by following a narrow boardwalk. Some of the dunes have been partially fixed by vegetation but as you near the beach, the sand is free-flowing, endlessly shifted by the strong westerlies Guincho is famous for. Wildlife enthusiasts should consult the information board at the start of the walk for a detailed rundown of the area's flora and fauna. But if you're here to spend some quality time with a loved one, then enjoy a leisurely stroll through one of the region's most beautiful and romantic stretches of coastline.
