I had the best three days stay at FreeHostels. The location is very well connected and is at at walking distance from Metro and Bus stations. There is a good supermarket just in front.
The staff was amazing and very fun loving. We had Christmas Party, Pizza night, Pasta night in the hostel, during which I could make some new friends, also the staff mixed up with us very well. The Bar offers some good drinks one can enjoy with friends. I will definitely book FreeHostels when I visit Rome next time.
