Ana's apartment is in a great location, 10 mins stroll from Sol, Sevilla and Banco de Espana and very close to Retiro park and the Prado Museum.
A small but stylish space in a great part of town, with a superb selection of restaurants close by. I was using it whilst working in Madrid, however this would be equally good for those on vacation due to the apartment's positioning. Should you need to get the Metro, Anton Martin station is a few steps away connecting you to the rest of the city.
Finally, communication with Ana was first class, she was very responsive and helpful.
