Clean, beautiful, stylish apartment in a great neighborhood-very central and interesting mix of residents - old, young, all nationalities. Numerous shops and restaurants nearby. Davinia always got back to us right away with any questions and was very helpful and friendly. Nice oasis in a busy city. I would not expect to sleep 4 people there unless one of them is a very small child, there is only a small pullout from the couch for sleeping. (One of our group of 3 slept on the couch) Awesome shower. Nespresso machine but no capsules for it, you can buy them from one of the nearby shops (we left a few there). Kitchen facilities are everything you could want. No trash bags provided but luckily we had an extra bag. TV did not appear to work with the wifi but we only tried it the first day, too busy after that. We were able to walk anywhere we wanted to go, the furthest was Atocha at just under a mile. The area is hilly. I would definitely stay here if I returned to Madrid - overall wonderful stay!
