Location, location, location! We had a fabulous stay at this apartment, located just a few minutes' walk from the Casco Viejo, the train station, and all of the main sites in the city. It's on the third floor of a beautiful older building with quite a lot of charm. Another major draw is that it is QUIET! The host is super helpful, punctual, and communicates vey effectively, and she made our stay in Bilbao quite enjoyable. I definitely recommend a stay here on a trip to Bilbao!
