Unfortunately, we were unable to use the terrace for three out of the four days we stayed at this AirBnB because the gate was malfunctioning and the host did not address it in a timely manner. Apartment Barcelona (the host) is a larger organization with well over a hundred AirBnB listings, but they were slow to respond and then non-responsive to messages in the AirBnB app, their email address, and their website-specific help portal. Apartment Barcelona gave us about a 12% refund of our stay after we contacted AirBnB support.
Note that if the gate malfunctions during your stay and gets stuck in the locked position, there is no natural light available in the living and dining area of the apartment, as there are no other windows in the common areas.
This was our first time in Spain and the last of two cities we were exploring. We hoped to spend time on the terrace to share meals and wine for a slower pace and ended up staying away from the apartment as much as possible because of how dark it is with the security gate stuck shut.
The two stars are for the cleanliness, the comfortable bed, and the updated bathroom and kitchen. Please note that while the amenities list on Apartment Barcelona's AirBnB listing includes bag storage for early arrivals, this is not the case. We used a third party service that was excellent and allowed us to wander the city ahead of check-in time.
This is the most disappointing experience we've had with an AirBnB. For the price paid, we should have stayed at a hotel, which we will when we visit Barcelona again.
