This was my first experience with air bnb and I wasn't disappointed.
Gemma was a wonderful host, who waited for me at the apartment for over an hour when I got lost and didn't make it on time as we had arranged. She gave me a map with tips on places to visit and good places to eat.
The apartment was beautiful, as described, very large and spacious, clean and in a very convenient location. It was well equiped and homely. The area was friendly and busy, surrounded by shops and tapas bars/ restaurants, and safe for a female to walk around at night. It's very close to public transport with the metro station only 5 minutes walk away, as is the shuttle bus to the airport. We chose to walk everywhere in Barcelona however, and given the central location that was easy enough to do too.
I thoroughly enjoyed my stay here and I'd be happy to recommend this to anyone.
