Great location just a short 5-minute walk to the beach and a 10-15 minute walk to the main old town with plenty of restaurants, bars, and cafes.

Felt very lucky, no reason to complain.

The bed at Koisi Hostel was incredibly comfortable, allowing us to sleep like babies throughout the night. The staff was nice and genuinely helpful, providing us with useful information about the local area. We loved the modern and clean facilities, making our stay truly enjoyable. The nearby local bars offered delicious pinxos, which were far better than the typical tourist places. We are already planning our next visit to San Sebastian and Koisi Hostel is definitely our top choice again. I highly recommend this hostel for its exceptional quality and comfort.

For the price, Koisi gave us great value with a comfortable room and helpful staff. The location was convenient, close to the beach and with good bars and restaurants nearby.

The breakfast option could have been more varied.

The Koisi Hostel was clean, new, and close to the beach. The lockers were suitable for backpacks. Staff was friendly and provided helpful recommendations. The bathroom was private and breakfast was basic but sufficient.

Nothing, no complaints at all.

The location of this hostel is great, with a short walk to the beach and a pleasant stroll to the main town area. the staff were friendly and helpful, making my stay more comfortable.

This hostel lacked a social atmosphere, making it difficult to meet other travelers, especially for solo travelers like myself. It would have been nice to have proper cooking facilities.

I recently stayed at Koisi and had a fantastic time. Whether you're a solo traveler or with a group, this brand new hostel caters to everyone. The staff went above and beyond to make my stay comfortable and enjoyable, even refilling the parking meter for me. The location is just a short walk from a stunning beach, and the free breakfast and bar area were great additions. The room, although a bit small, had ample storage space and a separate bathroom. a nice place with friendly staff and a good vibe.

We had a fantastic stay at a hostel in San Sebastian. the staff at Koisi was incredibly friendly and always available to help with recommendations and directions. They made our stay more enjoyable and hassle-free. the private room we stayed in felt more like a hotel, as it was quiet and peaceful. It exceeded our expectations, as we were not expecting the typical hostel atmosphere with parties and loud people. the room size was good and offered great value for the money. the breakfast, although small, had a good variety of options.

Don't have any issues at all 😊.

Convenient location near beautiful shores. Helpful staff and bar with drinks and snacks. Clean rooms with comfortable beds, powerpoints, and lights in bunks. Free parking available overnight. Laundry room and two terraces, including a nice rooftop for morning yoga.

I recently stayed at Koisi in San Sebastian for a few nights. The beds were comfy and the rooms were quiet. The staff was friendly, and the rooms were always clean. I liked that the shower, toilet, and sink were separate, making it easy for multiple people to get ready at once. The location was great, close to the beach and just a short walk along the coast to old town. a pleasant and convenient stay.

I would be happy to recommend this hotel.

Our stay at Koisi was fantastic. The hostel's location was perfect with a beautiful beach just a short walk away. The hostel was clean, well-decorated, and had secure spaces for our belongings. We loved the convenience of the bags on the wall by the bed head. The staff, particularly Eric at reception, were friendly and accommodating. The hostel also had a nice breakfast and food bar downstairs. I would highly recommend Koisi for a great stay in San Sebastian.
