Yolanda’s place is very good budget accommodation. It is in a fantastic location for Bilbao - nearly on the river halfway between Guggenheim and old quarter.
Yolanda is the most helpful host you will meet on air bnb. She offers help a lot but she really means it. She will wash your clothes, take you to bus or train, whatever you need - she will go above. If you want less contact you can just tell her she will accept. She is very tolerant and very honest. I can guarantee this from my experience there. Also you are sharing the small place with her & another guest but this is NOT a problem as she is incredibly considerate and gives you all the space you need.
