Andoni is AMAZING! The apartment is great, has all amenities needed when travelling as 2 adults & 2 children including cot. But the best bit is Andoni himself. Great local travel tips. Transport pass is provided and local maps. He is super quick to respond with ideas and suggestions of where you can go.
Apartment is in a great location; we walked to the Guggenhiem pushing a pram and then came back through the old town for tapas and drinks. Recommend.
