If you want a real local experience in Madrid, this is a great option. The location is perfect with lots of bars, restaurants, tapas places and beautiful pedestrian areas walking distance. The flat is very well designed, minimal and very clean.
A couple of things which weren't a problem for
us but might be worth mentioning were: there was some noise coming from the street and a bar next door during the night, there are two electric heaters but don't expect the temperature inside the flat to be very hot, the bathroom door doesn't close as it's been cut too big for the frame. If you can live with that, I strongly recommend the place. Alicia is very kind and accommodating too.
