It was my first time traveling by myself (Female, 22), and I was kind of scared of staying in a hostel. But it turned out to be great! I stayed for two nights in a 4-bed female dormitory, the staff were very friendly, the people staying seemed very nice as well. Free Breakfast was great :))
For people who’re worried about their things, they have lockers (you can bring a lock, or buy one at front desk), and a luggage room for bigger things! The place seemed very clean, and they offer bedding and towels! I got lucky with roommates and they were quiet and nice too.
