An Israeli friend of mine recommended this hostel to me and said it was "absolutely wonderful". He wasn't lying. Location, location, location. Perfect. Close to everything in the old city and being next to the Jaffa gate (with tour starts, banks, restaurants, info) means that newer parts of W-Jerusalem can also easily be reached on foot or by tram. The roof is awesome. Just go upstairs and have a look.
Staff is super friendly and flexible and will advise you on pretty much anything, wether it being places to eat, bank services, holidays (August/September is filled with them and some places close down earlier or close completely), tours, buses and sights. They will also have change for the coffee machine, do your washing for 50 NIS and tell a few stories and jokes. ;)
The rooms are fine. And just great for this price. All in all I stayed in 3 private rooms w. ensuite bathroom and shared bathrooms and everything worked out fine. Everything was clean and tidy. There was no air-con in the rooms, only fans, but it didn't matter (I imagine it could be a problem for some in july/august though).
The only thing I missed was not having mobile and internet connection at the same time (since the wif-fi only works in and around the cave-like lobby where you lose gsm signal). It might work if you step outside though. But, this was a minor thing really. Another thing.... there can be many steps to your room... and no lift. This however was no problem in my case.
I was travelling alone and the Citadel was just perfect for me. I highly recommend it. :)
