Overall we had a nice experience here. On the plus side, the apartment is in an amazing location, walkable almost everywhere. The apartment is even bigger than I expected. Everything was super clean. The negatives: the apartment didn't have any central heating system, instead having one wall heater installed in each room. The bedrooms warmed up well, but the living room remained cold for much of our stay no matter how warm we turned the temperature. The check-in process was not ideal, as we had to specify exactly when we would be there, and if we were late we would be charged, and if we arrived after 9pm we would be charged. We ended up having to sit outside for about 30 minutes waiting because we got to the apartment ahead of schedule. There was no option to leave the bags in the apartment after we checked out, so we had to bring them with us as we explored the city. Overall it was a comfortable apartment and we enjoyed Barcelona.
