We had a wonderful stay in Bilbao at Marta's place. She was very kind, generous, and helpful. She was very responsive to messages and texts, and she was flexible with our arrival and departure times. The place is just like the pictures, and it provides easy access to the old town (less than 5 min walk). Marta gave us all the essentials and then some, and she gave us some good advice. We used her parking space in a private garage, so that gave us some peace of mind. There was some late-night noise on the street right below the balcony, but by closing the windows, I got back to sleep.
This was my first experience using Airbnb. Marta has set the bar high for other hosts!
