It's hard to rate this hostel as it was the perfect place except for bed bugs. We only discovered them 3 days into our 5 day stay when the bites appeared. It made it difficult to sleep for the last 2 nights. Having had bed bugs before I recognised the signs but of course it was too late. When I returned home I found 2 live bugs on my case so I washed EVERYTHING at 60c and quarantined (in black plastic bin liners) the things that couldn't be washed for 5 weeks in the 25-30c sun. I suffered from extremely itchy bites for about a week after as did my 2 companions. I wouldn't have stayed there if I had known about them because bed bugs are the biggest pain ever and so hard to get rid of.
Apart from that the hostel is brilliant. The workers couldn't do enough for you and served mint tea the moment you walked through the front door. They wouldn't let you lift a finger and were very helpful with prices and helping us get into the local hammam for a good price. They even went to buy things for us that we never would have got at the same price being European.
The common room area is great (as is the terrace) for meeting people. The rooms are pretty small and we didn't spend much time in them. They don't assign you a bed so I would sometimes return to find someone else in the bed I'd been sleeping in. With only 3 bathrooms you had to form a queue sometimes. The breakfast was plentiful and there was so much we had to ask to take it with us.
We always felt safe and though there were no lockers people left valuables lying around and there were no problems but we were all young students so I guess it depends on the type of people.
