This is a lovely, homely, comfy, quiet apartment in a great location in old town by the wonderful Ribera Market, close to tram stop and metro, and to shops, cafes and restaurants. The beds are so comfy and you get a good night's sleep as so peaceful. The Guggenheim is 20 minutes away along the river which is a pleasant walk
Amaya was so helpful and furnished us with guidebooks, transport info, food and drink recommendations, and a Barik card for discounted travel as well as booking a table for us at a popular local restaurant. She even came out to look for us when we got lost!! For us, we think if you are coming here by public transport, easier to take airport bus to bus terminus then tram to Rivera market and apartment is short walk away via outdoor escalator. We had a wonderful few days in Bilbao and were lucky to have found this lovely apartment.
