I had a really great time at Bibiana and Gigi's for 2 nights. My flight landed at 6am in the morning and I asked Bibiana if I could drop my stuff off at her place before the official check-in time, which she was very generous about. Bibiana wasn't home on my arrival, and the lady who keeps by the door in day times at the entrance gave me the key and helped me open the door to the house.
The attic, which is for the guests, is quite spacious, and everything in the house including the bed and bathroom was clean and accessible. The bed is very comfortable, too. The window in the attic leads to a spectacular view from the rooftop. If I had to pick a problem, I would say the ceiling isn't high enough for a very tall person but I had no problem (1.65m; 5ft6)
The location of the house could not be better and Bibiana is very welcoming. I wish i had more time to get to know and talk more. I would definitely stay here again if I ever come to Madrid again. Muchas gracias!! :)
