The apartment is small but well set up for two people, any more and it’d be crowded. It’s in a great location, very close to the Anton Martin underground station, and close walking for the sites of Madrid. The hot water system is small, but allows for two quick showers. Comfy bed, and comfy couch to relax on. It is up many flights of stairs, so be aware if that is going to be a problem for you. All in all, A good place to stay!
