My husband, daughter and I stayed there for one night as we arrived at the train station and had a night stay over before our flight out. The place was very clean and stylish. It had 2 twin beds (together) and a twin trundle bed. A set of three units with its own small locked off lobby were located on the 2nd floor, at the end of a hall. They were a new, stylish oasis. The building itself was big and a bit dated, but there were automatic lights everywhere and the location, across from the main Atocha train station, and in front of a big taxi stand was amazing. Atocha is near many of the other main attractions in Madrid like the museums and Retiro. The studio itself has was new and modern with a big flat screen TV and new furniture and remodeled bathroom. It was surprisingly quiet given the location. Arnoldo was a super responsive host.
