I've spent 2 months in Maria's flat and I felt like home. The flat is perfectly clean, very cosy and very well equipped with everything you may need. Plus, Maria and her assistant Susanna are very kind and available to help with any request. Location is great too. The flat is located in a quiet and residential area, just 15 mins walking from the heart go Madrid (like Chueca or Malsana) and the closest tube station is just 2 mins from the flat. Of course the swimming pool of the building during summertime is a plus! The only thing I can complain about are the neighbours on the bedroom side, who are extremely noisy and their kid screams almost the entire day, but of course this has nothing to do with the flat itself or Maria. I would recommend the flat 100% (except for neighbours!)
