We stayed for 2 nights in Koldo's apartment and everything went great. Koldo waited for us on the checkin day even though we arrived at 22:00. The apartment is spacious and has all amenities needed, even for larger groups or families. Another strong point is the private (and free) parking that saves you from all the hassle of finding a spot. In the end Koldo was really kind to allow us to do a late checkin (waves were pumping so we really wanted to enjoy our last day) and he also offered us an extra night for free, so I would give 6 stars for hospitality. Keep in mind also that the apartment does not have wifi (that might be a point to be addressed in the future) and also that spanish is the desired language for communication. All in all, I would definitely recommend Koldo's apartment
