IRafaels studio was very clean and nice and the communication between us went very smoothly. Unless you only stay a couple nights I think, though, it is more accurate to say that the studio is suitable for three people rather than four since the fouton is rather small.
The wild roosters in the neighhbourhood are not for everyone, so bring ear plugs.
The air-conditioning did not communicate with the remote. Rafael tried to fix it but without luck.
There might be periods during the weekend with short time leasing-guests in the other part of the house which may result in people partying some but I just went over and asked them politely to keep it down which they did, so no biggie, really.
The check in-procedure was super easy and I felt very safe in the neighbourhood which is rather close to the beach which is a big advantage. Shopping and restaurants are nearby too.
