Not only is the Hi1898 Spa an incredible way to relax, disconnect and enjoy some R & R, but it's located in one of the most beautiful hotels in the city. Situated directly on La Rambla, you can't get more central than this. The Spa is in the old storage cellar of the Philippines Tobacco Company and the architecture helps to provide for a truly peaceful atmosphere. The spa offers a range of services including its heater pool, whirlpools, therapeutic fountains, sauna, steam rooms and a variety of amazing massages. It's restricted for those 14 and older. After you're finished lounging, go to the terrace where you can get some of the best 360 degree views of the city.
