Feel Free Rentals run a very efficient set of apartments in the centre of San Sebastian. The entire check in process was done on a website and an app for the front door. I didn't have to actually meet anybody in order to access the apartment.
The apartment was clean, modern and stylish. It had comfortable furnishing and a lovely little kitchen and bathroom. It felt very new and was a pleasure to stay there.
The apartment was in an incredible spot and when you leave the building you are directly on Calle Mayor with the famous Baroque Church in view at the end of the street.
