Great appartment. I would say for 2-3 people than 4. The second room would be for one person instead of 2, to me. I was there alone so it really felt like home. The area is probably one of the best in Madrid. 5 minutes from the beautiful parc, and very quiet area. Lots of supermarkets and small restaurants. The appartement is a rooftop so the terrasse is really nice witu furniture. I needed a checkout a midday and it was accepted. Everything was clean. The only tricky thing was the shower temperature management because but this more related to the building than the flat itself, but nothing terrible. Great place I recommend.
