Erda.  You are correct - Chueca Club (Cra. 13 # 83-19). It has a pretty exclusive door policy so they tend to draw in a more moneyed crowd, hence the working boys. Just wear a clean shirt and a fake gringo accent and you are good to go. Or invite me to do all the talking

I wish someone would expound on this topic also. I'm sooooo curious to know what's going on.

Casa Sanchez looks quite nice. Though not a 'gay hotel' like Adam, it is apparently gay-owned and gay-friendly, presumably accustomed to same-sex couples using the lower courtyard pool and rooftop hot-tub, outside pool table, etc.
However, being gay operated says little about tolerance for the parade of sex work guests for which some of us want an unencumbered privilege. 
As I reported earlier, locals less comfortable about being seen obviously in a "get down" role in a hotel context might be more easily persuaded to come in for a drink and billiards (how inocuous and macho is that?!) or swim or jacuzzi, breaking the ice, and eventually moving towards the privacy of the room. 
Similarly, Palacio has a rooftop sunning and pool area. 
You might even pack a few extra swimsuits. 
TAU Casa Conde by Paco's (aka Grand) would be a place to which you would have to be more direct inviting the guy to your room, and entering is publicly more visible. While not necessarily a great place to stay, it would be affordable to some as a secondary base exclusively for sex. It is more definably geared for that, for female guests of male punters (but sex hetero tourism is usually highlighted over MSM), though a regular hotel.

I'm trying to decide on my next fun jaunt. Sto Domingo is on the list. This MP gym sounds intriguing, but why is it being mentioned here? Just eye candy? Just a place to work out? Or has there been confirmed hookups from here or, even better, action right here?
