Enrique was very propmt to answer to all my questions. He wasn't there to receive us but his friend was very nice.
The apartment is located at maybe 20 min walking from Placa Catalunya, and also there is a bus stop right in front of the building. The area is quiet and you have a supermarket in front of the building. The place looks just like in the pictures and we had everything we needed. We enjoyed our stay there and if we are coming back to Barcelona, we are definitely picking the same place.
