There were two couples in our group and the layout was excellent: lots of space. Very clean. Comfortable beds. Well equipped. Cristina was able to accommodate our early arrival (leaving luggage in the flat until cleaning from just departed guests was complete) and a late departure (no incoming guests that day). The best feature is the location with public transportation very nearby and a plethora of restaurants ( many, highly rated ones), of convenience stores, fish markets, pubs, etc. There is no significant sign of tourists: you are living among citizens of Barcelona but only a couple of stops on the metro from many tourist areas. Cristina was in touch daily via email seeking to assist, guide or resolve. She was a great source of information. If there are 2-4 of you and this flat is available then I'd recommend you take it.
