Totally recommended apartment! The location is perfect, next to the Guggenheim-Museum, in the heart of the old town with great bars and restaurants all within 5 minutes walking distance.
The apartment is a wonderful combination of working old elements (high ceiling, wooden beams) into a more modern interior (blue table lighting at the entrance).
Smart upgrades make the apartment nicely usable: the thin doors to the balcony let the little noise in from the street, but in the bedrooms these habe been replaced by tightly sealed doors/windows, making sleeping noise-free. Well done, Jaime!
The host is super helpful, waiting by the apartment when we arrived and very fast in response to questions, even organizing our taxi to the airport for our return.
No doubt, full endorsement!
