Really lovely comfortable and homely flat within a few minutes walk of a Metro stop on two lines, and the bonkers brilliance of Gaudi's Sagrada Familia. Stayed for five nights. Easy check in and out - Andres was very helpful and flexible. He also provided initial milk/juice/bread/cornflakes which meant that after a late check in I didn't need to worry about breakfast.
Andres is very friendly, and sent lots of useful information in advance of the stay. He even provides a printer in the flat which was very useful for printing tickets, and umbrellas in case it rains.
I would very much recommend the flat, and it is a definite step up from some of the more sterile flats I've seen.
