Javier's appartment is very well located, about 1 km from Atocha. It is a 2-story appartment, perfect to stay in Madrid. It is close to the Acacias metro station and 3 blocks to the Embajadores metro station. The only warning I could think of would be for people who might have a problem to go up the stairs to the bedrooms, which are upstairs. Other than this, it is an excellent choice for a stay in Madrid.
