Quite simply, Anna's apartment is the nicest AirBnB rental we've stayed in, out of about a dozen over the last few years.
The space is immaculate, and unlike most AirBnB's we've rented it is furnished appropriate to it's size. Most we've stayed in either have too little furniture or cheaper furnishings that aren't quite comfortable. Or they're crammed with stuff that makes the space feels cramped. Anna's place feels just right.
The kitchen is well-equipped as well and we regularly fixed our meals there.
The two terraces are wonderful spaces, as well. Several evenings we returned to enjoy vermouth as the sun set over the hills.
The washing machine was easily accessible, which was important to us on a nearly two-week stay.
We never met Anna, even though she lives downstairs. But she maintained contact with us via email to make sure we had everything we needed.
A word about location: we've stayed in Barcelona apartments in L'Eixample and Sant Antoni, where you walk out the building door to find an abundance of restaurants, bars markets and shops. Anna's apartment is in a quieter residential neighborhood. It's a five-minute walk to the Metro, less to a bus stop. The nearest stores are probably five minutes away as well, and it's a 15-minute walk to the bustling part of Gracia. Also, it's on the hillside, so almost any walk will require a climb. None of this was a problem for us, and we enjoyed the neighborhood, but if you're used to other parts of the city you'll want to be aware.
Would highly recommend!
