Bego's apartment was amazing for the four of us. The location can't be beat as we could walk to everything in the city. Also there was free parking in the apartment which let us easily rent a car and drive back and forth around Basque country.
We were met at the apartment late (after 11pm) and were given a whole introduction to the city and many great recommendations. The apartment was clean, modern, and spacious and had everything we needed to have a great time.
