I didnt see a thread on this place. Here´s what I know from a recent visit.

address: Rua da Quitanda 74
tel: (21) 2224-5322

I was escorted to the elevator, rode up directly to the 5th flr boite. No check-in at reception, no key, no robe. Earlier that afternoon I had walked up the stairs to the 2nd flr reception, was told it opens 4pm, received "20% de desconto na entrada" card, & prices:

entrada 30
40min 110
60min 125
90min 155

In the 5th flr boite no one had on robes. 7 gdps working, none caught my eye. Later I explored flrs 2-4, found an empty boite on the 2nd or 3rd flr. Locker room, bathrooms, showers, etc weren´t quite finished yet.

For 1 cerveja & entrada I was charged only 20 probably cuz the facilities weren´t fully operational.
