Carmen and Luis’s place is wonderful. The location is about a 10 minute walk (slightly up hill) from Estacion Puerta de Atocha, which is the train stain, and also the location where the 5 euro airport bus drops you off (this station is the end of the airport express bus). My room, the bathroom, and kitchen were spotless. Carmen works hard at keeping things clean due to her pride of ownership. The unit is very well located relative to the main center sites……all within walking distance. I can’t say enough about the wonderful stay at their place. If/when I am back in Madrid, I will certainly try to stay here.
