Marathon

Liked: The whole place was really nice. Loved the breakfast and the fact it was open before the marathon x
Disliked: Not really usex to sharing but they were all great. Except somone pinched my towel which was special to me. My faithful running towel from Hardalot 10k in France x

Very good

Great location, friendly owner!

Liked: The host was very sweet and accommodating! There were no women-only dorms available. I requested a women-only dorm if possible, and she did her best to accommodate that even though it wasn't guaranteed. I told her it was more of a preference, but she still was able to make that happen for one of my nights (which I appreciate very greatly!) They also had a live band play for one of the nights, they were so entertaining!
Disliked: (Context: I'm a digital nomad that was working during my stay). There wasn't really a good place for me to work on my laptop. I was able to work in the reception area, but people would get me confused with someone who was working for the hostel. It wasn't the best place for a nomad, but otherwise no other complaints.

Passable

Everything was on point

Liked: Su was an excellent host.Easy location for the castle, buses, bike hire.The bed (bunk) was extremely comfortable.

A good central location in...

Liked: A very central location in Caernarfon. Easy-to-find. Easy check-in and check-out. Su is a very friendly host / owner and showed me around the facilities. I had a secure place to leave my bike. Facilities were good. A hot shower to freshen up after a long cycle ride from Dolgellau. A great breakfast downstairs in the bar. Co-owner Matthew was great to talk to before I departed the following morning. Bedroom was 'cosy' - it is a hostel, after all. But, the bed was comfortable and clean. I hired a good-sized towel for the shower. All-in-all, I would recommend this place for a good-priced stay in a very central location.
Disliked: There's nothing I didn't like about this hostel.

Superb

Very good

Liked: Staff was very friendly and lovely. I really like that breakfast was included. I liked the beds, they were comfy and gave you some privacy.
Disliked: Some storage in the room to put all of your stuff would have been a nice addition.
