This was our best air bnb experience so far.

--communication was excellent from beginning to end; Mike contacted me multiple times before and during our stay to help set up our arrival, to personally meet us (and help carry a suitcase), orient us to the property and to Barcelona, and he facilitated an easy checkout. He even left us maps, gave advice for dining, running routes, and left wine and bottled water for us to enjoy.
--the property itself is beautiful, new and with modern design and decor. Very clean and full of light. There are 2 bedrooms, each with an en suite bathroom with shower, plenty of storage. There is a washer/dryer, full kitchen, dishwasher, all of which were used during our stay and worked great.
--very comfortable; windows are insulated so there was very little noise; AC worked well, beds very comfortable.
--neighborhood is full of great places to eat and shop; we were close to 2 metro stations, each within a 5 minute or less walk, so it was easy to get around to the major sites like Sagrada familia, Park Guell, and the Picasso Museum; the walk to la rambla is about 10 minutes, and about 15-20 minutes to Barceloneta/beach

This is a perfect place to stay in Barcelona and Mike was a great host. I would stay here again when visiting in the future. I would recommend it to anyone who is able bodied--you must be able to walk up 3 flights of stairs!
