I will recommend anyone going to Madrid to stay with Henrietta. The place is central, but quiet. You have your own bathroom and sitting room.
You have a separate entrance for late at night. Henrietta goes especially to the baker's for you every morning! She is available whenever needed and pleasing. The bedroom looks bigger in the picture than in reality but it's still comfortable enough as well as the bed. One of the cats is quite chatty :-) We were very pleased with our stay.
