This is a really cute little flat in a great location and I highly recommend it. We stayed for 2 nights but I wished from the moment we arrived that we had more time to spend in Bilbao, because it's a really exciting city and the flat is really comfortable. It's quite small, but we are a family of four and we had all the space we needed. The decoration is really cool, and there are lots of personal touches, so it doesn't feel like one of those soulless airbnb places, it feels like a home. The hosts are extremely kind and thoughtful, for example they lent us a travel card which gave us a discount on public transport. We loved the area, because it's lively and very central, but if you don't like the hustle and bustle of a big city you might choose to stay somewhere else. Our favourite bar was Peso Neto, http://www.pesoneto.es/ . Make sure you book ahead if you want to eat out, because everywhere good gets booked up. We were lucky to get a table at Restaurante Arima, Bailén Kalea, 33, 48003 Bilbao. The food was really good. We also ate at Dando la Brasa but it was disappointing and expensive.
