We stayed at Bibianas place for 4 days and for us it was the perfect room. Everything was as mentioned. The Location is insanely good - you can reach everything by foot. Bibiana had always time to give us recommendations for restaurants or locations to Go to and she was always up for a small chat over our small daily adventures, which we appreciated.
If you are not afraid of hights, we can highly recommend Bibianas Place for your trip to Madrid! :)
