I had the double room. It is very basic, a bed, a small table with 2 chairs, 2 bedside tables, a bin, a mirror on the wall and some hooks for hanging clothes.
The bed was very comfortable, you can adjust the heating to your liking so my room was always comfortably warm.
The shared toilet facilities on my floor (3rd floor) were great...clean and always stocked.
I cannot comment on food or the showers as I did not use those options. But the showers are accessible next to the bar, but you will have to go down the stairs and past the restaurant/bar to get there.
Be aware this is a hostel and it will get very noisy on a Saturday night, there is no soundproofing.
Bit the Sunday and Monday I had the floor to myself so it was quiet.
Overall I had a good stay there.
If you book any tours with a pickup service, they will pick you up outside the entrance.
And do have a hotdog or two from the van down the road, they are good!
