Fabulous 8.8 From 66 reviews

Good 6.0
a Good hostel but far a way to get to .
The location is out of town you need to take a bus number 18 or 25 to get to from city center and when you arrive you need to walk an walk up long steps to get to the hostel also you need to pay for your own towel and you are not allowed to bring any food from outside .
Jeffrey, us1 night trip
Very good 8.0
Really clean and modern. No kitchen but there are microwaves and toasters. Rooms are small, so prepare for that. Very helpful staff. It’s not far from the beach, but prepare for a walk up the hill!

Good location, nice hostel.
Good location. Friendly staff. Quality bunk beds (the bottom bunk doesn’t shake when someone climbs to the top). Kitchen has decent facilities. Near the beach, along the Camino route.

Very good 8.0
Great value, comfortable family rooms
Great value stay, room was clean and comfortable, and location was extremely safe and fairly convenient. This was our first hostel stay as a family, and we were pleasantly surprised by the room. It was more spacious than I expected and the beds were very comfortable. Our only issue was that we were there along with a large group who had special parties in the common area/dining room, which seemed to limit both the hours and the menu that were available to other guests. It impacted our experience a little, but was not a dealbreaker. Our stay was still very good, and I would not hesitate to recommend Koisi to other travelers (I actually already have).
