Arina's apartment is one of the nicest AirBnB's we've stayed in. It's spacious, well-decorated, and comfortable for a couple or a small family. The apartment is modern and well designed, with lots of amenities, including a high end washer and dryer. The bedding is very good - memory foam mattress and pillows - perfect for getting a good sleep and getting over jet lag. The management company was very responsive and friendly and met us to check us in, and the welcome package was very generous with coffee, juice, milk, and snacks which came in handy when we woke up with jet lag..
The best part about Arina's apartment is the location. It is along one of the best pedestrian avenues in Barcelona with close access to shopping and great restaurants. It's far enough from Barcelona's tourist action, yet close enough if you're there to see the sites.
The cons are it is the first floor on a major street, so you do hear street noise. Be prepared to wear earplugs if you are sensitive to noise. That's the only trade-off.
There are very good blackout blinds, but three of them did not work in the living/dining area, which made it less comfortable for our children who slept on the pullout mattress in the living room. Those definitely need to be fixed before I would recommend booking or before I would stay there again, especially if your guests will sleep in the living room.
Again, overall great stay!
