Cow gate hostel was completely different to what I expected. They have kind of flats with 3 rooms each you share with other tourists. The rooms are just normal hostel rooms with 4-8 or more beds in it. It was nice staying there and clean. Unfortunately a little loud but because pubs were just opposite the street and the heating was not working but a member of staff was helpful to get it work. Definitely recommendable and really good location
Belford hostel was great. I was completely surprised by sleeping in and old church being Belford hostel nowadays. It's a great hostel with a big kitchen/common area and an own bar. It is located in the east of the city so quite a walk to the main sights but if you like walking its good. I guess it is around 20 minutes walk to the castle but not too bad. The staff was really nice. The room I was in was not really big but none is in a hostel. Unfortunately no windows as it is inside the church.
The hostel was good. It has a great location directly opposite the train and bus station and as Killarney is not big you could basically walk everywhere within 5-10 minutes. The room was ok but unfortunately you could hear every noise in the hostel. The room was not too big for 6 people but ok. The common areas seemed to be cleaned every day but unfortunately not the room. Nevertheless I was still satisfied with it. The staff was nice and 24 hours available.
