I am giving this place 5 stars based on the outstanding service the host provides. The flat is well designed and well equiped for short stays. Location is good because it is walking distance to everywhere you want to within the Madrid city center.
However I can not really say this was a pleasant stay for me, because there was too much noise coming from the neighbours during the night. Starting from the first day (new years eve) there was party at the flat next to the bedroom. I hoped that it would stop after one or two days but unfortunately it did not. Neighboors continue to play music, play kareoke and watch tv loudly till the morning. Thanks to my host which really tried to solve the problem but best solution for me was sleeping at the livingroom. I suppose that the apartment has a sound insulation problem that is compounded by the fact that neighbours do not respect for the others.
