The apartment was great, and it was a great location (breakfast place around the corner that I would highly recommend), close to the subway and supermarkets. The rooms were clean and fresh and modern and the terrace was big and really nice!
HOWEVER, the place is made out of cement, lack of carpets and no heating left us FREEZING! We visited Barcelona at the end of November (It was around 17ºC during the day) It was extremely cold in the loft, when we asked the hosts if there was anything we could do to warm the place up we were told to use the air-conditioning on a higher setting, we tried to leave it on for hours but it didn’t work. We had to put towels down on the floors to make it warmer. I can imagine that this apartment would be perfect in the summer!
Also, the key pickup was a bit further than we were told, it was about a 10 min walk from the loft but that wasn’t too bothersome.
