This place is, in a word, lovely. Plenty of natural light, a cozy atmosphere, and an excellent location. Up the street there is a line of restaurants serving tapas and/or pinxos. The Metro is about a 5 minute walk from the porch, and two-three stops from La Rambla and just a few more to La Sagrada Familia. The reviews I based my choice on and the listing itself were both 100% accurate in the best way possible.
As a hostess, Rosa was thorough, hospitable, and warm, all of which were very welcome after a long day of traveling. She greeted us as if we were old friends reuniting, and gave us plenty of options to keep us busy.
I cannot recommend this place enough!
