Koldo’s place is in Errenteria, a nice town near San Sebastián. The place was nice, modern and clean. I only met Koldo when I checked in, sine he was out of town during my visit. You can easily reach San Sebastián with the metro which is close by. There are also buses, though I only used the metro. The town itself is quite lively at night with lots of pintxos bars and sidewalk cafes.
