Alba was very responsive before and throughout our stay, and met us when we arrived later than planned at 10pm. Dealing with her was a pleasure.
However - the apartment needs attention. Cupboards, doors etc. are generally in bad repair; master bedroom windows cannot be darkened so sleep after 7:30am is difficult; secondary bedroom lacks airconditioning and was too hot for the kids to fall asleep in; and the washing machine and water boiler share the same electrical socket: difficult gymnastics are required to plug one or the other in, and the boiler won't heat the water while the machine is running (a full wash-dry cycle takes 6 hours). Floor was pretty dusty, with some ants in the kids' bathroom as well. With some more care and attention it could be charming, but it's not.
Given the premium price, we were expecting much better.
Location is ok - The Sagrada Familia is obviously across the street, but the immediate neighborhood is not great. There's a could of supermarkets and a metro station very close though, and it's only about 20 minutes' walk to the beautiful Eixample area.
