Sergi was a very friendly person. We stayed there for 4 nights and Sergi contacted us everyday to make sure we are okay. He also provided us some good recommendations on food and places to visit. We had some difficulties trying to get to the airport as our flight was a very early flight, but Sergi helped us to call the taxi and arranged the transport for us perfectly. My friends and I were very happy and satisfied with the apartment provided, and it truly made our stay at Barcelona a pleasant one!
