Quite an unexceptional flat in the center of Barcelona (biggest plus: really good located and not noisy at all) in a typical old building, the flat itself has also some parts that are due for renovation but overall condition is OK.
Some downsides: located in a narrow street, first floor, therefore you will miss some daylight, flat was also quite chilly in March, especially the bathroom that has no heating at all. Master bedroom was fine, second bedroom with two single beds I would only recommend for childs.
Check-in and communication was professional but as in many other AirBnb locations quite impersonal.
