We would like to thank Ana for being a wonderful host. I really appreciate all the prompt communication. Even though Ana was unable to pass the keys to us when we arrived, the place to get them was just next door. The apartment is nicely located to be able to access all the attractions by foot. Previous reviewers commented about the size and darkness, since the apartment faces the courtyard on the 1st floor of the 4 story building. While this is true, we spent all days visiting places and few days returned for lunch. Considering that we have quite large houses in the US, at least for us, we don't mind to stay in a tiny city apartment abroad for 1 or even 2 weeks - great place for the money.
I may be wrong (so it is better to consult Ana), but we found that arriving from airport to Atocha station by Renfe is the most convenient way especially when you have heavy or bulky luggage. The best place to buy food is at the large supermarket on a plaza by Lavapies metro station. Apartment has a very good stocked up kitchen.
Everybody in our family liked this little flat which really was home away from home. Thank you, Ana! Definitely recommend Ana's apartment to stay in Madrid.
