Iñaki and Ana went far and above what I would expect from an average airbnb host. Communications were excellent. They have a delightful space in Bilbao and our welcome was warm and genuine. We were met by Iñaki as we arrived in the square and walked to the apartment. There we met Ana and provided with a lot of very useful information. They run a bespoke travel service as well and we were able to employ Iñaki in this capacity for an excellent orientation/history/ pintxos tour of the city that evening. Iñaki and Ana even provided us with a Barik travel-card (rechargeable at any Metro station) which proved very useful.
You should be aware the apartment is on the third floor without a lift. The staircase is broad and well lit. Wi-Fi is good and fast. The space is spotlessly clean, spacious with everything you'll need. Soundproofing is excellent. The area is lively, safe and full of bars & restaurants. There is a small, well equipped supermarket downstairs.
Iñaki and Ana's contribution to our visit was to make a good holiday in Bilbao a great holiday in Bilbao!
Should we return to Bilbao we would have no hesitation in staying here. Highly recommended hosts.
