On the surface, the apartment has everything you need for a comfortable stay in Barcelona. The location gives you easy access to Sagrada Familia, small markets and public transportation. You also have A/C, access to a free washer & dryer in the building (with detergent), Wi-Fi and kitchen (no microwave).
My main issue with the place was actually the bed, which I feel is a huge component of a comfortable stay. It seemed like you could actually feel the springs through the padding which made it very difficult to sleep. My boyfriend did not get a good night's rest all 5 nights that we were there.
Lastly, it was missing a few nice touches that I have come to expect, particularly since this place is run by a property management company (soap in shower, condiments for kitchen, trash can in bathroom). Also, as mentioned in another review, the communication prior to arrival is odd. You are routed through separate e-mails outside of Airbnb requesting your arrival details, but when I would respond including questions I had, I would not get any answers for my questions, but would receive additional questions from them.
I think this spot was a good value compared to other places in Barcelona (which is probably why I chose it), but I would not stay here again.
