We had a nice stay at Joaquín and Natalia's. They were quick to accommodate us. They gave clear instructions for the self-check-in and were very responsive throughout the entirety of our stay. The apartment itself is very small, but it is well-equipped. The terrace is nice, great sunset view.
The only thing I would note is that the bathroom is not the most comfortable. The shower had no door, which could result in a bit of a mess and a chilly shower.
