This Airbnb is in a great location for those looking to stay close to Diagonal/Eixample (we were in Barcelona for work). For us, the location to be best aspect! It's a large place that comfortably fit our family of four. We ran into an issue with a broken air conditioning unit for one week during a heat wave, but it later got replaced, which was appreciated. As another reviewer mentioned, there are limited kitchen pots/pans and no amenities provided, so be prepared to bring all of your own salt, pepper, soap, kitchen towels, etc. The weekday cleanings were nice, however. We found the apartment to be very dark because of all the dark floors, walls, and cabinets, and there were a few times we tripped over the dark step in the master bedroom.
Overall, this is a good place to stay if you want to be in that neighborhood of Barcelona, but be prepared for a somewhat darker space and to bring all of your own supplies.
