I slept 5 nights at Singer109, in two different rooms. 6 ppl room was nice, boxes with locks worked well!
The other, 8 ppl dorm with kitchen was bigger, and there was more space per person. Sheets and towels were always nice and clean. Most of people stayed out late (or to early morning hours), so there was ofcourse a lot of traffic, but thats hostels work. Didn't bothered me!
Employees are always there for you to help, and bar is always open. I recom this place for my friends!
