The appartments where we stayed were really gorgeous and very clean. The are located really close to the Sagrada Familia and two underground stations. Lots of really nice bars and shopping possibilities are also very close.
Nick was the best host you can imagine. He gave us a lot of useful information about where to get best Tapas, etc. He organized a taxi transfer from the airport and back without any problem. He was very nice and charming and we will absolutely stay with him.
