This was our first time traveling to Barcelona for our group of 4 (two couples). The unit was in a great location on a quiet street, which offered easy access to public transit options and plenty of places to eat and drink. The space itself was also decorated very nicely, and included comfortable beds, a cute little couch/table area for hanging out and a wonderful rain shower head. (I personally enjoyed spending my mornings in the sun room!) It was definitely enough space for all of us.
That being said, we were hoping for a bit more amenities from a Plus listing. While there were some basics on hand - such as shampoo and conditioner - others were pretty limited. For example, we only had one towel each for our weeklong stay, a few coffee pods, there was no body wash and one of the beds was missing a comforter.
It is also worth noting that the couple that stayed in the inner room did hear a lot of noise from other units in the building, as well as the stairwell.
We also ran into some issues with the check-in process that made us feel uneasy. While we had requested to keep all communications within the Airbnb app (as recommended by Airbnb), we were required to connect with a third-party building manager via text upon arrival in order to check-in. At the time of check-in, she also requested to see our passports in order to take pictures of them (when this information had already been shared with the hosts through the app prior to our trip.) When we declined to share our passports with the building manager, it did not seem to be an issue, but it was a bit unexpected for our group.
In the end, we enjoyed our stay in Barcelona very much. However, by offering more amenities and changing the check-in process, our stay would have been more comfortable.
