Hello everyone, Ill be in Barcelona with my partner for 3 days between friday and monday in a couple of weeks. Our monday flight leaves at midnight and we wanted to spend a few hours on monday afternoon at a gym or a spa (preferably both).

I searched the forum for Gyms and Spas with no luck.
I would really appreciate if any of the locals or travelers whos been to BCN and found a day gym and spa could point me to some of these places.

Were staying at the center of BCN right next to Plaza Catalunya.
Thanks in advance.
