Me and a friend stayed at Alex and Audrey's place for three nights a few days after the New Year. Overall, we had a very good experience! The room itself was very clean, spacious and had good decor! We also liked the fact that there was a private bathroom (which was quite modern, I might add). The location was very central near lots of restaurants, shops and many of the main tourist attractions. Not once did we use any form of public transit during our stay. Most of the places we wanted to see was within a 45 minute walk. Would definitely stay here again if I ever go back to Barcelona!
