Had a lovely stay. Location is absolutely perfect, you can walk to Guggenheim in 15 mins and you are only minutes away from Casco Viejo and the old town. Tons of bars and restaurants all within <15 min walk. Apartment was clean and as described, but as it is in the city, it can be a bit noisy at night since it is close to bars, though this was fine for us. The showers are very small, as you often find in cities in Europe, and might be tight for a large person. Apartment is on the first floor, but there is also a lift in case you cannot manage the short flight of stairs. Check-in and check-out was simple and Javier was very helpful and even left a bottle of cava and some cakes for us to enjoy. Included was a parking space just across the way in a garage. Overall, a great experience and would recommend!
