We had a lovely 3 nights staying at Fermin suite. It is perfectly located in the heart of the old town and very close to a safe underground carpark. The flat has been recently renovated and is impeccable. The attention to detail is excellent and thoughtful gestures were left including hand gel/face masks. My husband and I really enjoyed our stay here and the team were very prompt with the communications. We would highly recommend this flat to anyone looking to stay in San Sebastian.
