Concha is THE nicest person ever!! She is very responsive and provides excellent information about your travel plans and siteseeing tips. Her place is quite far from city center but if you like to walk.. the walk by Miramar and Concha Beach is absolutely beautiful!!! Also its extremely quiet at her place, since it's in a residential area and you're just sharing it with her, so you'll be nice and rested.
LOVED SAN SEBASTIAN!!!!!
