We recently had a wonderful stay at Luis and Terese's apartment in the old town in San Sebastian. Luis' welcome was warm and very informative regarding places to see, restaurants, bars and other things to see in San Sebastian and the surrounding area. He was available during our stay to assist us in anyway possible if we needed him, which we did a couple of times.
The apartment was perfect for the 2 of us - on the top floor and with a lift which does make it a lot easier if you have a lot of luggage which we did!! The apartment is surrounded by pintos bars but once in the apartment you cannot hear a thing! The facilities were perfect with everything we needed for a short stay.
I highly recommend this apartment if you are going to San Sebastian.
