This is a comfortable and clean flat in a nice neighborhood!
Main attractions like the Sagrada Familia, Casa Battlò and Casa Mila are within walking distance, 15 – 20 minutes. Nearest metro station is only a couple of blocks away, 5 minutes. There are several nice restaurants in the neighborhood, some do take away, and if you prefer to do the cooking yourself, there is a supermarket just next to the entrance to the apartment building, and a tempting food hall around the block.
The flat had 5 beds; 1 double bed and 4 singles. They were all comfortable with firm mattresses. There are 2 bathrooms with walk-in showers. There is a well-equipped kitchen with a big dining table.
One note of warning about soundproofing: we were never bothered by the neighbors, but we unfortunately disturbed one neighbor when we arrived on our first day. This was late at night and had we known, we would have been more careful. We apologized and never heard from him again. We were 4 ladies in our fifties staying in the flat while attending a workshop in Barcelona; we are usually not loud.
The hosts were very kind in helping us with information on how to get to the flat from the airport upon our arrival in Barcelona, and they always replied promptly to our inquiries.
