Our experience here wasn't great. The bathroom felt unclean, water didn't drain from the shower or in the sink properly so dirt collected around the rim and it also meant the bathroom was always wet.
The furniture was also not as pictured so it wasn't that comfortable. We also didn't have running water for half a day in the morning during our stay, so we were not able to wash and go out, so we lost half a day in Barcelona.
The apartment also had no cooking oil, salt, pepper, etc. so we couldn't use the kitchen properly during our stay, even though that's why we choose to use Airbnb. It was also sometimes a little chilly in the apartment, despite putting the heating on.
Overall, our stay was not very comfortable.
However, the location was good and so was the hosts communication.
