Fernando was an informative and generous host. The apartment is on the 4th floor of a nice building 1/2 block from Plaza Callao. It is wonderfully situated to visit all parts of Madrid. There is one private bedroom with an almost queen size bed, walk in closet with a washing machine and a full bath. The second bedroom is a curtained off end of the living room with a very comfy bed (as pictured on the airbnb site). There is also a 1/2 bath off the very nice kitchen.
We enjoyed our stay there very much.
The only issue for us was the noise-both from the street (until @ 12:30am) and also from the courtyard off the bedroom as many of the windows would blow open and closed repeatedly during the night. We are not used to apartment living so this was difficult for us.
