The apartment is amazing and we felt at home immediately. Ibon picked us up from the underground station (Euskotren) and showed us how to find the supermarket, which would have been a challenge otherwise. His apartment is not too big, but has all necessary appliances and his DVD collection is amazing for rainy days or lazy evenings. Errenteria offers a nice change of pace from the San Sebastian buzz while it's still only 15 minutes by Euskotren, there are lots of bars (with Keler beer, nice), but not too many restaurants. Very much recommended! Thank you Ibon!
