Everything was perfect. Maral and Alfonso were very friendly and welcoming. It was easy to communicate with them and agree on arrival/departure time. I arrived quite late in the evening, and they even bought me food for breakfast. The studio flat is newly refurbished, very well equipped (tv, kitchen, wifi etc) and very comfortable. It's right in the centre - close to Plaza Santa Ana, near many lovely restaurants, cafes and bars and the main museums. I stayed in Madrid for 5 days and was very glad to have found such a nice place! I can only recommend it.
