This is a very good, clean and comfortable party hostel. But know that if you intend to go to bed early and get up for a tour you are very unlikely to get enough sleep. If you don't mind that it is one of the best hostels I've stayed in New Zealand
This hostel has a great atmosphere. The terrace is a great common room, some days you even get to have fish barbacue! Great staff, very friendly and helpful. It's the perfect compromise between party hostel and a quiet one. Meaning if you feel like partying somebody will go out for sure, but if you need to relax you can stay on the pillows on the terrace.
It's clean with decent beds and bathrooms. It lacks a common room to meet people and there is no kitchen to lower the expenses in Rome. So this is a nice B&B more than a hostel.
Great hostel, a lot of character. The staff was very helpful and I had tons of fun. The showers were good and clean, the beds were comfortable. I will definitely go back.
