We stayed here for a month. We would stay here again in a New York minute.
Pros - Location is perfect as it is the Gothic quarter and close to the Park and Barceloneta Beach. Heating/Cooling worked great and you can open windows to get a fresh breeze. Communication was rapid and productive. Kitchen and Bathrooms and Washer/Dryer all wor worked great. Apartment was spacious and well appointed.
Cons - Hot water worked fine but the amount was less than two Amercans were used to.
To summarize, love the place and will stay again when we visit Barcelona.
