Issac was extremely friendly and welcoming. On arrival, he gave us really detailed information on what to do in and around Bilbao.
The bedroom in his apartment is newly decorated and the beds as fantastic - like a 5* hotel. The private bathroom is also modern and immaculate.
The apartment is centrally located within easy walking distance of the train station (about 10 mins), as well as the old town and Guggenheim Museum. We would definitely recommend Issac's place in Bilbao.
