Luisa's place is pretty much perfect for exploring Bilbao. It is situated in a really nice neighbourhood with lots of shops and close to everything of interest (especially if you want to have easy access to the Guggenheim museum), the room is large, clean and comfortable, and so is the bathroom! It is also close to the airport bus. Luisa allowed us to leave our luggage at the apartment at 10AM while we explored the neighbourhood. She is really lovely and has the cutest dog. I couldn't recommend this place enough!
