Our stay at Txaro's house was lovely. It is such a cute, adorable little house and has a nice terrace/backyard to have your breakfast in the morning or to just sit outside and get some fresh air. She is so kind and helpful. It is very close (within 5 minutes of walking) to the San Mamés metro station so you are well situated for public transport. The truth is that you can walk to most of the city from Txaro's place. I would recommend this Airbnb to anyone wanting to visit Bilbao.
