We have abit of a problem finding the apartment, but once you know the way it is just a short walk from Atocha renfe. Location is good since it is near metro stops and Atocha renfe and there are supermarkets and restaurants nearby.
Apartment is clean, nice and cozy and facilities are adequate. We are a group of 3 and don't feel cramp in this apartment since there are 2 bedrooms.
Apartment is value for money and I definitely recommend it considering it can accommodate up to 4 people and its good location. The only downside is there's no lift and apartment is on the 4th floor
