If you are younger than 25 years old, go for it absolutely as it is cheap with a great location. Otherwise, you may not if you specially suffer of sleeping in a noisy environment and in non-comfortable beds. It was incredibly crowded with young people, teenagers, and children. My room was just beside toilets and bathrooms, so people were passing and talking and making noise till I fall asleep at 1 am. I was alone so the bed at the end was just non-comfortable, but for two person it was actually a trap! as there were two single mattress beside each other where 70% of one of them was actually floated in the air without a surface beneath. So, if you lay on it, you would fall ground :))
The rest was all nice. The reception was very friendly. There is actually a very nice bar for the hostel that is open till 5 am and the kitchen is open till 10 pm. The location is great. The interior design was vintage and very pleasant :)
