We had a good time during our stay in Barcelona. The bed is very comfy and the check in and communication was easy. Location is great for park and beach and near to metro and supermarket, but the area itself isn't the nicest compared to other places in Barcelona , but we knew this before we booked as we were with our 2 years old location was more important than having nice shops and bars!
The apartment is fine as a base and was perfectly clean but it definitely feels a bit unloved and run down. We also found the street noise outside very loud at times (street cleaning and late night bin collection etc) and also struggled with noise from the upstairs neighbours. Not them being particular loud , just the way the noises carry in the apartments.
So like I said, the apartment was ok, but we would look for something else if we return to Barcelona.
Worth noting that Gonzalo was great, responds to messages really quickly and fixed the shutters for us immediately when we asked.
