First up, this is in a great location - lots going on with cute eateries close by, near a canal, by greenery and you can easily walk into the centre. It is well finished and has generally been thought out. Service was friendly and helpful.
I was in the 20 bed female dorm on the ground floor; this had minimal space to move and the main door opens directly onto the reception/lounge so sound does enter, and it also causes an issue if the bathroom door is opened at the same time. The bathroom door does not close quietly and most guests didn't think to not allow it to slam, so it can be disruptive. But, bed chambers do block out light, they have enough space and places to put your things, and lockers are spacious. However suitcases do hang out in the corridor so making the space feel and be smaller.
In terms of cleanliness, it was always being cleaned in the middle of the day, though a lot of people means it isn't immaculate. The bins could more clearly state 'plastic' and 'general' to encourage less waste.
The lounge is a cute comfortable place to hang out; I used it to do work, be on a live call, read, and eat dinner (there were no qualms about bringing in your own food even though they served snacks and drinks).
As an older traveller (34) and wanting somewhere quiet to be able to do my work and also be in town for the marathon, it was a good setting. I was comfortable, even if with little sleep due to the noise some people made and this can't be helped in such a large dorm.
