Natalia Y Roberto's apartment is located in an old building in a character area. It is very well insulated from the noise outside and even when the airconditioning malfunctioned the ceiling fans kept us very comfortable. The apartment is very well equipped and beautifully and tastefully furnished. The apartment is a quick walk to the Lavapies metro station, a 15-20 minute walk to the Museo du Prado and 10-15 minutes to the Reine Sophie art museum. There was a good coffee shop attached to the Mercator San Fernando on the square but we had to walk a bit further for the good eating places. There is an excellent and large supermarket opposite the metro station is located. Natalia was a superb host dealing with all our issues when the air conditioning failed and with excellent communication for our arrival and departure. I would totally recommend this place to anyone travelling to Madrid.
