I recently stayed in Rafael’s apartment with my two 15 year olds (boy and girl) for 4 nights - the unit was perfect for our needs - clean, well appointed and in a great location for exploring Madrid. The two bedrooms (one with an ensuite bathroom) plus the Murphy bed made it possible for us all to have our own space and still hang out together, have meals at the kitchen table, etc. The building is very nice and secure and as an interior unit is very quiet. It is close to two metro stops (Sol and Tirso de Molina) and within walking distance of Palacio Real (the royal palace - a must see!), Plaza Mayor and the Mercado de San Miguel (great experience/tapas). Rafael was very responsive to questions before and during our stay, and check in was easy.
