Very authentic stay in the apartment smack bang in the middle of Casa Viejco. Very much part of the beautiful old town street living experience. We were there when it was a mini heatwave and the apartment was a very cool escape from the heat. The balcony where you watch the world go by and feel immersed in street life was great. Some fantastic cafes, bars and pinxtos, all within walking distance. Did a lot of walking to see various museums, bridges, markets but you also have good transport links on your doorstep. Love it and also now love Bilbao.
