Me and my boyfriend, we stayed one day and one night in Bilbao. Haiz is a very warm and sweet host. She welcomed us at her home and took care of us very generously. We felt comfortable from the first second. The apartment is big ant very clean, we even got our own bathroom. Haiz has a friendly dog who loves to be pet, if you want to.
The apartment is well located, closely to the subway station, but also in walking distance to the old town and city center. We had a great stay and would recommend it for everyone. If we come back to Bilbao, we would definitely stay here again.
