My husband and I have stayed at 12 airbnb's in the US and Europe. I do A LOT of research before making a reservation and consider physical features, host availability, price, location and reviews. So if you are reading this and thinking about a Barcelona apartment, you get the benefit of MANY hours of my work :-)
My husband and I rented Jordi's apartment for 10 nights and we highly recommend it. Communication with Jordi is swift and clear. He is a welcoming introduction to the city. The fact that he tracked our flight and met us at the door was wonderful. He sat with us and a map and marked locations of museums, restaurants, grocery stores and also customized it to our interests.
The amenities of the apartment are as described and in photos. With real estate in the US, the top of the list is often "Location, Location, Location." And Jordi's apartment really is ideally situated. We walked everywhere, and when we needed the Metro, it was a just a short walk away.
If you read to this point, and the apartment is still available during the days you want to visit Barcelona... I suggest you book... before someone else does :-)
