Reserving a hostel

[mocunni]

This prolly wouldn't be urgent but I am going to Africa on Thursday and need to plan a trip to Paris beforehand...

Searching the hostels, you can only make reservations for one person in a single, private. If I am traveling alone, is there no way of taking advantage of cheap multi-person room rates?

I need to make reservations for something soon, but cannot afford the cost of the private rooms.

Thank you kindly.
