The reservation and check in process was excellent- very professional and the team that met us at the door was great and available throughout our stay for questions/concerns. The apartment was very clean and had everything we needed for our stay. It was next to a great restaurant and market and walking distance from a few main attractions (Basilica, La Rambla, waterfront, etc.). The only reason I gave it a 4 rather than a 5 is because it is a very busy complex and we had some neighbors who liked to be very loud into the early morning (not the teams fault at all, maybe just bad timing with a loud group). The group did trash the patio but we were able to call our contact and she came up right away and cleaned up their mess which was great!
I'd stay here again if I come back to Barcelona!
