Myself and some friends had a great time in San Sebastian, largely due to the wonderful apartment we stayed in.
Checking in was very easy, despite doing so on a Saturday when the office is closed. The instructions were clear and detailed and we had no issues getting into the apartment or parking our car in the private parking space.
We had lots of dinners out on the terrace and took full advantage of the large, sociable living space. The kitchen is great to cook in, very large and kitted out with everything you need.
The apartment is a short walk away from the beach and the centre, it is a pretty walk and is very flat.
I would highly recommend this apartment to a group of friends or a family.
