Perfect location (right in the Casco Viejo but quiet at night, transportation ideal, the Ribera Market next door, and the best bread in the street!). Belen was the best upon our arrival (she kindly helped us with the luggages and the car).
The place was very clean, which was really nice.
Of note: The kitchen is tiny, so it is not possible to really cook there + the bedroom with the single bed does not have a window.
