I visited Montevideo 643 piso 7, a.k.a. Magic Hands, this afternoon at about 1pm. A lovely lady with fair skin and light brown hair, probably early 20's, named Soledad, introduced herself. The only other person I saw when entering was the receptionist. I didn't ask to see a lineup as I was impressed with Soledad.
I had the hour-and-half massage. It was just as Havrum described. I got a professional massage in a very clean room with a massage table. The shower room was quite clean as well. I couldn't ask for more. About an hour into it, it turned more erotic. She gave a nice handjob. I didn't ask for anything else. She wore a massage uniform and never removed it. I just wanted total relaxation with no bullshit and that's what I got. She played nice soft music and we had a friendly chat. She seemed to enjoy her work. She left the room to prepare the shower for me and I left the money on the table along with a $30 propina. I took a shower, got dressed, and as I was leaving I passed maybe four girls in the lobby. They all seemed to be dark-skinned Paraguayan types. I'm really not into "latinas". I like the European-looking girls. So, I was pleased to get Soledad. Your mileage and preferences may vary.
Based only on this one visit, I'd say this is a good place to get a serious professional masssage with some teasing and a handjob thrown in at the end, in a clean environment.
