The apartment is very clean and crisp and very well decorated.
The apartment is located next to a public park which is worth visiting with lots to see and do. There is also plenty of shops, bars and restaurants within walking distance and there is good transport links to every other part of the city.
We were four adults and it was more than big enough to accommodate us. We spent our time out sightseeing but the apartment is well designed and could be used for preparing meals if guests desired to do so.
Would recommend to anyone wanting a base of operations for visiting Madrid.
