For a stay in Bilbao during the winter months, this apartment is ideal. We stayed over the Christmas and New Year's holidays as a couple and took several day trips. Since the tram is just outside you can get to the bus station and both train stations in just a few minutes. The old town and museums and shops are all in walking distance. We walked home from dinner easily at night including 2 different Michelin * restaurants. And the view to the scenic river path is very nice while having breakfast.
Since we had the windows and shutters closed at night to keep the apartment warm (with the heat thermostat on) it was quiet for sleeping. The kitchen is modern with all the necessary pots and pans - we used the dishwasher and washing machine during our stay. The WiFi connection was excellent and no problem getting work done on our computers or streaming to TV (we brought our own Chromecast) while sitting on the comfortable chairs and couch. Plenty of storage space and hangers and looks like the photos.
The value was very good versus a hotel and because many places are closed over the holidays, it was much better to have our own apartment to cook and relax. Blanca was responsive to our questions about the Airbnb as well as advice on travel and special events. Since we took the airport bus it was a slight hassle to get the keys from another building and then walk to the apartment. Overall we highly recommend Blanca's rental for a city break or week stay in Bilbao as the location is perfect and the apartment in excellent condition. We would stay there again in the future.
