The room does NOT have air conditioning. That's only in the living room. Really unpleasent discover. I tried to stay one night but I had to open a window loosing all my privacy, since the window is facing other windows. From the bathroom I could literally shake hands with a guy who was at the phone.
I contacted Airbnb and they were very helpfull to help change place.
The owner does not speak english.
Other than that, the place is clean, check-in was easy. The house position is really close to the sagrada familia so you are in the center but it's a really tourist area (the prices of everything are higher) but the metro is really close.
