Since the apartment was renovated last year - it was bright and fresh and very clean. An added bonus is that there were two full bathrooms for a three bedroom apartment, which helps a lot when you have more than three people staying in one accommodation. All the amenities were available and true to the description on the website.
This apartment is NOT owner occupied, but Lisa and Galder live in the next building over, so it is very easy to coordinate. Galder met my friend and I at the apartment with the keys, explained a lot of things in the area, and even gave us a printout of recommendations and places to go around the area. This was extremely helpful to us.
The ONLY recommendation I have is that we struggled to find a corkscrew/bottle opener for all the wine we bought. :) This does not affect my review, but we finally found one at a shop nearby and left it there for future guests.
I would definitely recommend this apartment for anyone visiting San Sebastian!
