The apartment is very convenient to get to from the Madrid airport as it is located literally across the street from the Sainz de Baranda metro station (with an elevator that can take you from the train platform to the street). The apartment building is very nice and secure and walking distance to many stores and restaurants and anything else you may need. It is a nice, safe residential neighborhood. The beautiful Retiro Park is walking distance and the center of Madrid is easily accessible by both walking and via Metro. The apartment is on what we from the United States would call the "second" floor and in Spain it is the "first" floor. The apartment is in great condition, very clean, and spacious. We were five people (2 adults and 3 children) and we had plenty of room. The kitchen is very well equipped with dishwasher, washer, coffee maker, dishes, utensils. There is a large dining table. Wifi. An added bonus is a huge terrace that runs the entire length of the apartment. There were bicycles, which we did not use, and a dryer (which we did not use because there were clothes lines and the clothes dry very quickly in the Madrid sunshine--so much better than drying in a machine). The shower was great, excellent pressure, and always plenty of hot water. Great communication with Nati and she is a very kind and considerate person who offered a lot of great suggestions for things to do in Madrid and places to go. Overall, it was a great experience and we would definitely stay there again. Highly recommend!
