Neptune's Town Hostel is a large but peaceful accommodation on Bishop's Lane just off of New Street.
This hostel is tucked away from the Main Street but is close to the National Park and like everything in the small town of Killarney, is close to every place of interest. I would recommend Murphy's on Main Street for food and a drink. also, if you decide to go to Muckross House, bike there as it is 10k to the actual house. The directions that the hostel provides are not really directions. Look it up on Google Maps before you come. It is only a 7-10 minute walk to the hostel from the bus/train station.
The rooms are hotel like because you are given key cards to enter your room. It is really nice having bathrooms in the bedroom. The bathrooms are a bit tight but manageable. Also, there is no Wifi in the rooms at all. The free Wifi and Internet are only in lobby not in the rooms.
The hostel has a large eating area and self serve kitchen. The kitchen provides tons of dinnerware and silverware, about six oven burners, and lots of pots and pans. The smaller reception area and common room which holds the one computer lack space and comfort but serve their purpose. Most of the people staying in the hostel only stay for one night or only use it at night so the smallness isn't a problem. There is also a TV and book room that is not used very much but looks comfortable enough.
This hostel should be treated more like a hotel: for sleeping and eating. Go out to the restaurants and pubs to meet people and to do your planning. The staff are very friendly and full of information. Use them! Overall, this stay was very enjoyable.
