Alejandro was a very responsive host, and his place is well furnished and comfortable. The neighborhood is also really nice - away from tourists, but full of good restaurants. The internet connection is strong and I was able to use it to make work calls. The terrace provides a nice respite. The large door/window in the living room was nice and we liked keeping it open to see into the street.
Our main complaints are (1) that the listing says "A/C", but there is no air conditioning (we managed to find a fan to keep ourselves cool at night), (2) the bathroom does not have a walk-in shower, as we expected from the photos, (3) the bathroom was not as clean as the rest of the apartment, and (4) there was no toilet paper upon our arrival (they delivered it late the next morning).
