This apartment is superbly located with easy walking access to most of central Madrid. You open the door onto the busy street and are right in the heart of Madrid, but the apartment is quiet as it faces away from the main street. It was spacious enough with three bedrooms and two bathrooms for our family of two adults and three teenage children to be comfortable for our five night stay. Oscar (our host who met us at the apartment) gave us a map and suggested good places to eat and visit which was very helpful. There were milk and coffee pods supplied and a small supermarket was just up the street for other items we needed. We would highly recommend this apartment.
Note for future guests - there is a half flight of stairs (about 8 steps) up to the elevator so some luggage hauling is required.
