A sense of home in a foreign country
Lovely staff, clean and comfortable rooms and the beautiful San Sebastián to occupy your waking moments. I was very happy here and extended my stay. Ignoring the wonderful setting that is San Sebastián I struggle to fault my welcome and stay at this hostel. Having a fast metabolism i perhaps found it a little warm inside at times with the staff preferring the warmth of the recently past summer to the comfortable autumn temperatures.

Highly recommended.
Excellent place to stay. Was easy walking distance to cafés, restaurants or the bus system to get to downtown San Sebastian. The staff was great, the environment you felt safe and it was nice and quiet.
