The physical structure is very noisy. As we danced in the rented room, the door kept shaking and slamming; in the changing rooms: the same thing, it looked like it was going to fall at any moment. The acoustics were also not very good and the sound of the room leaked a lot, which could disturb other students. For the amount paid of 50 reais per hour, we expected at least a better structure and service, since the entrance staff is not very receptive. They even took a while to answer our questions via Whatsapp and, when we went downstairs, we found the guy using Facebook... He could have answered us instead of being on social networks, just a suggestion.
I think the only positive point is that the place has a lot of lgbt-friendly paraphernalia written on the bathroom doors, changing rooms and walls.
