There are quite a few saunas in Recife. According to the locals I talked to, all saunas in Recife are mixed. I have only been to three: Termas Boa Vista (TBV), Recife SPA Sauna (SPA), and Blue Termas. Personally, I would rank them in that order. Not sure you'll like Blue Termas, I did have fun the one time I visited but it was with another patron. But this was based on a visit, also I didn't stay long. Having said that, since it is so near, why not check it out at least 1 time?
Most of the saunas and gay venues are in Boa Vista area - maybe 20-40 mins Uber from you, depending on the traffic.
