About
Cats Hostel San Sebastian
Cats Hostel San Sebastian, also known as Koisi Hostel, sits in the quiet residential Barrio del Antiguo, a short walk from the shore. The building is only a year old, so rooms are up to date and equipped for the modern traveler – think key card access, soundproofed rooms, and air conditioning in many dorms and privates.
Guests consistently praise the helpful, warm staff and the hostel's clean, comfortable spaces. The on-site bar serves snacks, drinks, and breakfast, and the terrace and lounge areas invite you to linger. With both dorms and private rooms, it suits solo travelers, couples, and families alike.

In brief
What works, what to weigh
+
Strengths
4 reasons to book- Staff go above and beyond — Guests repeatedly highlight the friendly, helpful team who are ready with recommendations and quick to resolve any issue.
- Modern, clean rooms — The building is about a year old, so rooms and common areas feel fresh, with new furniture and thoughtful touches like personal lights and outlets.
- Free breakfast included — A daily breakfast of croissants, pastries, toast, juice, and coffee is part of the rate – a solid start before exploring.
- Great location near the beach — A short stroll to the shore and a scenic 20-minute coastal walk to the city center, with a bus stop about 5 minutes away.
–
Worth weighing
4 to weigh- Tricky street parking — On-street spots are hard to come by, so arriving by car may require patience.
- Quiet, out-of-the-way neighborhood — The hostel sits in a residential area away from the tourist buzz – peaceful, but longer walks to some attractions and restaurant hub.
- Shared spaces could use upkeep — A few guests noted the lounge area needs maintenance (e.g., broken foosball) and the kitchen could use a bigger fridge and more trash cans.
- Check-in ends at midnight — Reception is 24-hour, but check-in is only from 15:00 to 23:59, so very late arrivals need to plan accordingly.
