We totally loved Nerea and Karlos's flat. It's much bigger than it looked in the photo's tastefully decorated and very clean. We had a great welcome and lots of information about Bilbao. Coffee and tea were provided and milk and a few other basics for breakfast which was great. The flat is really central and although some of the other reviews mention noise we didn't find the flat noisy as the bedrooms are at the back. I would definitely stay there again and would highly recommend.
