The apartment is great. I stayed there with my husband, baby and my parents. The second bedroom is very tiny, basically just the bed so it's a little hard to have open suitcases but there's room in the living room or the hallway. The main bedroom is comfortable and it's super convenient to have the ensuite bathroom. We had a travel crib there for my baby and he slept great. The kitchen is also very convenient, it has everything you need. The location of the apartment is excellent, just a few steps from Puerta del Sol and Plaza Mayor.
