Huge complex in a historic building. Decent hours to coincide with work. Front desk staff is very friendly. Bring your own water bottle, or else pay for one in the locker rooms (10 pesos).

It can be a bit pricey. I paid about 500 pesos for 1 week ($60 USD). Not bad compared to NY/SF standards. read more
