As written by so many people, Nacho is a great host. Answers your queries promptly and provides additional details. Checked us in and explained to us the area and Barcelona. Also gave tips on restaurants, groceries etc.
As we were at the entrance of the apartment, I could traffic noises which were quite loud and went oh well, there goes a good night's sleep. However, Nacho has soundproofed the apartment very well. Couldn't hear a single thing inside the bedroom for 3 nights. Would recommend this place.
