We loved our stay here! My parents (66&61) stayed in the room with the double bed and they thought it was very comfortable. My boyfriend and I (22) stayed in the loft with the 2 twin beds & that was nice for us as well. The apartment was bigger than I anticipated from the photos. There is only one bathroom with a shower, but there is a second WC connected to the living room not pictured in the posting. The apartment is right near a pedestrian street & market. 20 min walk from Park Guell & 30 min walk from old town Barcelona, 15 min walk to Sagrada Familia. We walked everywhere we needed to go & also enjoyed eating in the non-touristy restaurants in the neighborhood.
Josep was very accommodating and helped us store our bags a few hours before check-in.
