We had a wonderful stay at Cristina's place! As a family with young kids we really appreciated the space and the ammenities the apartment offered. It is an easy walking distance from Barcelona Sants and quick access to metro trains. Plenty of cafes around and anything you'd need within walking distance. Cristina is a lovely, friendly host, communication is easy, and she was happy to provide whatever we needed. We really appreciated her generosity in holding our bags for us, and just being lovely to deal with. There is moderate noise from within the apartment building (earplugs for light sleepers), but overall a relaxed and easy stay.
