We enjoyed our stay at Federico's flat. It is on the ground floor in central Gracia in a quiet street. There is a good supermarket a 2 minute walk away and all the major sights are within 40 minutes. The flat itself was very clean and had all the basics for a 4 night stay. Federico was very nice and met us at the flat with helpful recommendations for our stay. The bed is comfortable and overall we had a great time in Barcelona.
