We enjoyed staying there, it is quite comfortable in there. There are a few things that might be improved. We missed a tea towel and the bed is relatively small for two persons.
Excellent features are: the air-conditioning, the wifi and the way the kitchen is equipped with the washing machine and the dishwasher. And the location is outstanding, very much in the middle of the city. Of course, with the sideffects that the nights can be quite unquiet. Still, quite a good place to discover Madrid.
