All I can say is that if all hosts were like Marta, the traveling world would be a much better place! The unit in Casco Viejo was incredible...very carefully restored architecture with 15-foot ceilings, hardwood floors, and a great balcony that allowed us to have a view onto the heart of the old part of Bilbao. It's very convenient to everything...in minutes you can be in the town plaza with all of its restaurants and bars, and there are two grocery markets within easy walking distance (less than 2 min). If you have a car, there is a public parking garage within a 5 minute walk. Marta came and showed us around the flat, despite the late hour (we got in around 10:00pm), and was very friendly. She even left us staples like coffee, fruit, and snacks that got us through until the next morning. One of the very best experiences I've ever had, and I have rented places all over the world.
