Xabier is the perfect host. The apartment is beautiful and a really convenient base for exploring the city and the coast. We stayed 5 days - the beach is so easy to reach by Metro. The local Pintxos and Txakoli kept us very happy and well-fed :) We found the people of the city very welcoming. Make sure you follow Xabier’s restaurant recommendations - they were excellent :)
We came for the Guggenheim but found so much more to enjoy.
