The Salamanca apartment was a wonderful place for our group to spend Christmas together. It was comfortable for 4 people and we were able to use the kitchen to make some wonderful meals together. The apartment is to the east of many of the major attractions in a quiet residential neighborhood although it was very convenient by Metro to get to all the sites as well as from the airport. The closest Metro is a block away and there are lots of markets close by. Although Sergio was out of town while we were there, he very responsive from the start with any questions and provided all the information we needed quickly. We enjoyed our stay in Madrid at his place.
