Very good, the only negativ comment that I could say is that I could feel the springs from the mattress, might be worth it to invest in new mattresses at some stage.
This is hands down the best Hostel I have been to. Superb location, right on the street with lots or restaurants and bars and only 3 min walk to city centre where there are lots of shopping and site seeing options. I arrived quite late but that didn't matter, the staff were super friendly and in general extremely helpful. The doors were clean, I didn't have a problem walking around barefoot, and the ensuite bathrooms were also spick and span. Will defiantly stay here again when I am in Rotterdam
Great location, could have been a little cleaner, inclusive breakfast was good. Rather loud at night.
