The apartment was very comfortable for me and my girlfriend and could accommodate a third guest (the third bed is in a common area attached to the kitchen). Ruth, our host, was absolutely lovely - she provided a very kind and warm welcome. The only downside to the apartment was the kitchen - the electric stovetop didn't work at all and there were no bowls. If not for this, we'd have zero complaints! The location is fine - there doesn't seem to be much going on in Hernani (as far as we saw, but we didn't spend much time there), but it's a 30-minute bus ride from San Sebastian and the bus stop is very close. There is a supermarket right next to the apartment.
