Our experience here was fine, not great. A number of issues:
1. We showed up and there was vomit all over the balcony. Terrible first impression of a place! They had someone clean it the next day.
2. The host was 30 minutes late to meet, so we were waiting outside with our luggage
3. "Air conditioning." It's hot right now in Barcelona, and we wanted AC. For this place, we were told when arrived that you have to hit a button by the front door every two hours to keep it going. Not ideal when it's cooking in the middle of the night. We thought that was misleading.
4. Washer/dryer. We'd been traveling for a while and wanted to use it. Note that it's not in unit, but rather a few floors up.

Overall, the place is clean (except for the vomit! :) ), in a good location (in El Born), and generally fine. The listing could have been a bit more transparent.
