we had a nice stay at this apartment. it is big enough for two, clean and near everything by foot (madrid main train station is only 900m away, and you can reach the city center in 15’). it is well organised (pans (and other stuff to cook) salt, towels, a/c, shampoo and gel) although some essentials were missing : pepper, oil, soap for the dishes, kitchen towel. the bed is faboulous and the communication with the host was easy and nice.
