"That was the best of luck".
We found the ad not long before getting to Donostia, and in a time (mid-August) when the city was literally packed. None of us three could have hoped for something better. The flat was immaculately clean, so nice and tidy, with very comfortable bed and sofa + an amazing shower! The flat is so central (in one of the very busiest streets), and yet absolutely quiet. Fanny and Inigo were extremely accommodating and helpful both before our arrival and throughout our stay. That was so generous of them. You really should not miss this accommodation if you plan to visit this wonderful town. Augur, and a presto!
