Luisa is a charming host, very helpful and friendly. She allowed me to check in early and explained everything to me in detail. Her place is beautiful and so well situated just 10 mins walk from the Guggenheim and across the river to the old town. There are many good restaurants and bars in the same street. The airport bus (cheap and easy) drops you just a few minutes walk from Luisa's place. The main train station is also just 10 mins walk away and the bus station around 25 mins. There is a metro stop only moments away. I highly recommend Luisa's place for a great stay in Bilbao.
