The apartment is amazing, I highly recommend it for your stay in Bilbao! It is very well located, near the Guggenheim museum, perfect to walk around and explore the lovely city.
The apartment was impeccable and the host went above and beyond to make us feel welcome. Communication was excellent and the house literally has everything! Everything for breakfast was provided: Coffee, milk, jam, butter, cookies and more, this was truly amazing for us. The bathroom is also fully equipped.
I would like to note that he also provided a crib and baby food for us, what a treat. Clearly the host truly cares about welcoming his guests!
