Ana Maria has been a great host. She solved questions and problems that I could have instantly. I couldn't ask for more in that aspect.
The apartment has a perfect location, at least it was perfect for me since my office was very close. There are 2 metro stations that are closeby: Tetuan station has a direct line to Atocha train station and "Puerta del Sol"; Cuzco metro station (the other one) is two stops away from "Nuevos ministerios", metro stop connected with the airport. So, the apartment is very well communicated with key places, as well as being located very close of the city center (walkable distances if you have time and nice weather).
The apartment is fully equipped and very nice to live in!
So, as conclusion, it is a really good option to stay in this apartment!
Thank you again Ana Maria
