Oscar was a great host. He met us when we arrived and gave us great tips on Bilbao. The apartment was perfect, lots of room and spotlessly clean. Exactly as described.
It couldn't have been in a better location, right beside the Ribera market in the heart of the old town. It's proximity to the tram line and the metro meant that it was really easy to get around on the excellent public transport system. (Well worth getting a Barik Card if you're going!) We would have no hesitation recommending Oscar and his apartment and would definitely use it again if we were returning to Bilbao.
