This is the first review I wish I was leaving five stars. We took a star off because there is and will be for a very long time a very active and loud construction site next door. They seem to only work weekdays but it is really loud.
Now other than that it’s a really nice place. The balcony is large, the place is clean, they are very responsive and accommodating, and they have hands down one of the best stocked kitchens with appliances and dishes and really everything you can need.
The location is perfect if you want to be close to the Sagrada Familia and the metro (get a multi day pass though! Totally worth it). And their communication is fantastic.
