We had a great stay at Maria's place. Maria is a very warm and kind host, we felt very welcome. The location is perfect, in the midst of the old city center, great for exploring this part of the city. Although located in a busy street, the room itself is really quiet. The room contains a refrigerator and a microwave, which was really convenient. The mattress is a bit smaller than the bed, that was not a problem for us but may be for other people. We do recommend this place for a stay in Bilbao!
