I booked two beds for a friend of mine for two nights whilst we were travelling around Italy for the weekend. Upon arrival we found the hostel clean, and it with a lovely view of mountains etc.
The rooms themselves are clean and spacious, you will not need a sleeping bag as linen is provided, however if it is winter you may want to request an extra blanket.

Breakfast is pretty awful and consisted of:
1 glass concentrated juice
1 coffee/tea
1 bread roll (stale both days)
1 jam spead and butter

Considering the price you pay, it doesn't matter if you eat breakfast or not. The bus is only a short ride into town, be sure to take advantage of the 5euro 3 day bus fare. Visit the Nella Bakery - the food is fresh, cheap and aithentic! Great for backpackers on a budget.

Surprisingly for two young girls staying at this 'Youth Hotel', we hardly saw any 'youths', it was mostly older european couples and families which was a bit disapointing as we were hoping me met new people.

Room and bathroom were fine, however service
on the front desk was not very good.
They were not there at 11 in the morning when I needed help
with directions to get to Milan.

When I did get to speak to someone he just walked out on me
and drove off closing the kiosk without giving me a chance to ask him my question. This was at 11am...Pathetic

Ostello della Gioventu Bergamo has just been a great host to 36 student travellers from UK (3 nights). The accommodation was very clean and I would certainly recommend this to anyone who needs 'hostel style' budget rooms. All rooms had balconies, most of which looked over the amazing landscape of bergamo. It is a hostel away from the main town, in a residential area, so if you stayed out late, you would need to get a taxi back. (approx 10 -12 euros).
Staff on reception were very helpful, and they all seemed to have excellent English - which put my limited Italian to shame.
Breakfast was: juice, bead rolls, jam & butter, with coffee.
The rooms varied in size (approx 4-8 people shared) with bunk-beds in the larger rooms - linen was also included. They had a shower/WC in each room and lockers were available - small deposit required for key.
Bergamo is a fascinating place to explore, and is an hour away to Milan by train, and slightly further to Lake garda.
If indeed you need to travel on residential trips with large groups of young people/students the hostel staff are happy to arrange coach transfers from/to the airport and for day trips out.
The daytime bus services are good, number 6 get you to the town centre/near train station and number 3 to the ‘old’ town.
I would imagine the hostel could get quite noisy when full of guests, walking down corridors and the general sound of chatting but then what hostel doesn’t? We have stayed @ Ostello della Gioventu before and plan to in the future.

The hostel is really cheap and the staff is quite friendly. The view is absolutely beautiful. But if you want to spend more that one night you should book a room with a small number of beds. I stayed in a room of 8 beds which was appropriate for let's say 4 beds. Breakfast is ok. You have good connections with Citta Alta (the old town) and the train station
