I would like to give the place 5 stars but there were a few things outside the control of the hosts that impacted our stay.
Firstly, it has two bathrooms which is great. They were clean and modern. The kitchen was also nice and clean. The living and dining area are small and sparsely decorated. They are in the middle of the apartment so not much light.
The bedrooms are fantastic - again, sparsely decorated but they have great beds and air conditioning. It was not particularly hot during our stay but is was nice to lower the temperature a couple of degrees.
The communication with the hosts was great. We were greeted by a third person who was very helpful and informative about the area.
The downside was construction in the building. There was jack hammering at times during the day and the lobby was used as a storage area for construction supplies. The noise was only during the day and only after 9:00am
The lift also broke down and we had to walk up four flights during our last two days. It seemed to stop working once the construction crew showed up.
I would recommend the apartment. The location is safe and easily to get around Barcelona.
