I booked this flat for friends, though I have seen the flat myself as well. Arranging the meeting with Ignacio was easy, you can forget about check in and check out when you aribnb, this is the best part. The house had a unique ambiente, not that you find in every building in madrid which has been a definite plus. The flat is on the 5th floor that gives you a nice view also to the surrounding streetart, while on the other hand without elevator you think twice before leaving the flat. :) The bed and the sofa could be somewhat more somfortable, but for a short stay they were fine. The location is also good, you can walk everywhere and there is a famous square with cafés and teraces just round the corner. Thanks for hosting Ignacio!
