The apartment was very small for 4 people, but perfect for our two days in Madrid. Everything was clean and we had everything we needed. It is located near the center of the city so we did not use the metro very often although the next station was only a 3 minute walk away from it. The communication with Elvira was very good and we did not had any problems. We had a great time and can recommend the apartment when you want to explore the city of madrid.
