Our stay was a bit underwhelming for us for multiple reasons:
the fairy lights and most of the other lights in the tent did not work so after it got dark we had to use our phones to light the tent up
There were a few insects in the tent, including a snail on the window and it was not possible to see any stars from the cabin because it is covered with a plastic cover
The common bathroom was very dark and also a bit smelly
There was black mould on the ceiling of the kitchen, which can't be very healthy
Stephen was not that friendly he seemed kind of impatient with us and when we had breakfast he made a big scene in front of all the other guests because we did not eat his bread but the bread we had left over from the previous day which made us feel pretty uncomfortable
Some positives:
The kitchen is well equipped
The common area is cozy, a good place to meet different people and there are many interesting and funny books
We were allowed to leave our luggage in the hallway until our bus came, non-supervised though
It is right next to the Connemara National Park visitors center and the beginning of the diamond Hill hike
The price was decent
All in all we would recommend staying inside the hostel rather than renting the cabin because it got very cold, there is very little space since the bed fills up the entire cabin (no room to stand up) and you can't see stars at all, even though we had a very clear night.
