El limonero is one of the best places you can stay at in Madrid. The area is hard to beat in accessibility, cultural and culinary offerings. You walk everywhere and public transportation is truly steps away.
The details Monika places while you stay with her are remarkable, from a friendly face and a remarkable chat to a glass of wine and a thorough description of the city, its history and quirks. You can walk to The Prado, Thyssen-Bornemisza and Reina Sofía museum in less than 10 minutes from here.
