Property Description

We are situated in El Antiguo (named precisely for being the original nucleus of the city), that lies adjacent to Ondarreta Beach and Mount Igeldo. It is a peaceful and elegant area, but also very vibrant. Home of some of the best tourist attractions such as the Palacio Miramar, Concha Bay, Ondarreta Beach and the Wind’s Comb, admirable work of the sculptor Eduardo Chillida and today one of the city’s most iconic and beautiful corners.

Chill out with a glass of wine at our bar or grab a snack from the café. Our terrace and our common room are top spots to meet new travelling buddies. And after a long day of sightseeing, there's nothing better than crashing out in front of the TV.

    Really great hostel, in a nice area of town. About a 20min walk from old town where there’s great food. Super close to the beach, staff very friendly and eager to help. Rooms pretty clean, lockers aren’t the biggest and a lot of people just left there bags lying in the floor but it felt safe and secure enough to do so! Would definitely recommend!

    Great hostel, not too far from the beach. Very clean and comfortable bed. Staff are very helpful and friendly, they also have a storage room where you can leave your bag after checking out if you want to spend the day in the town and can collect it when you leave.

    This Hostel is clean and modern and the rooms are designed quite well. The toilet, sink and shower are each in a separate space in the dorm rooms, so it is much more efficient when 4 people are using the room. There weren't many people using the bar/reception area while I was there, but it is a very nice space for eating a snack, planning your day, talking to the staff and checking your phone. It is a 30 minute walk from the bus station near Maria Cristina bridge, but you can walk the promenade.

    We didn’t have much time to spend at the hostel since we only stayed for one night. But we were received very warmly after a bad experience in Bayonne. Would recommend 100%

    The hostel was easy to find, in a great location and the staff were incredibly helpful. There was food available for breakfast and lunch (if desired) and activities like yoga on the beach, bike hire and info regarding surfing and other water sports. Price was a lot for a hostel in general, but for San Sebastián it was the going rate. The only negative was the lack of ease with air conditioning since we have to message someone at reception to turn it on each night.

    Like sleeping in a pigeon hole but cool none the less. Heaps modern. Perfect location for the main part of the city. Biggest downfall: no kitchen facilities!! Cannot easily backpack without access to even a fridge. Biggest reason I possibly wouldn't stay here again

    If you're wanting to just hang out at the beach in San Sebastian then this hostel would be great, just walk down the hill about 8 minutes away and you'll be at the beach. We stayed in the old town of San Sebastian prior to checking in here and we personally preferred the old town as it was a little more "happening" but this hostel is a great chilled out vibe. Staff were friendly and place was clean.
