The apartment is in a fabulous location, very close to the Sagrada Familia and it's metro station. There are lots of local amenities close by. The apartment was very clean and had everything we required. As we stayed over a week the cleaners also came mid visit which was appreciated. The apartment, like any old building in Barcelona I'm sure, is quite noisy with transmitted noises from other apartments. I was also very conscious of any contact noise we might be making that might affect the people below. We didn't have any complaints but I guess this is why a noise sensor is installed. I don't think this would be different else where. Over all an excellent stay with great help from Stay U-nique.
