Some things that you need to be aware of when you stay in a hostel in Rome are that whilst sheets are usually provided, towel may not be (so you may need to bring your own). Also, unless you're staying in a hostel that has private room capabilities, all dormitories and shared rooms, by definition, are 'open' to others - so cannot be considered 'safe', for the purposes of storing valuables. Therefore, if you have any valuables, it is a good idea to keep these in the available lockers (which are usually free, but may have a small cover-charge).

Lock-in or Lock-out policy at hostels in Rome

When staying at a hostel in Rome you do need to make yourself aware of whether or not the hostel operates both a lockout and lock-in policy. A lockout policy is where the hostel doesn't allow guests to stay during certain hours of the afternoon - so as to give the hostel operators time to clean the place up. A lock-in policy is where the hostel closes its doors at a pre-announced time of the evening and no longer allows people in - even if they have already registered to stay the night. Whilst the former of these two is rarely a problem, after all, you'll be visiting all the sights, the latter of these can cause a problem or two if you lose track of time whilst you party the night away in one of Rome's fabulous night-spots. So take care to note whether the hostel you're staying in operators one, or both, of these policies.
