Positives: Affordable, good size kitchen and balcony, well stocked kitchen, very close to buses and shops, quality welcome book, comfortable bed, nice size closet with enough hangers, nice small desk, good shower.
Negatives: The location was a bit sketchy. In an alley next to an adult store. It was also a bit hard to find at first - location on google maps was not accurate and had to rely on a series of picture instructions (which ended up being helpful in the end). Shared with two other rooms of random strangers and the walls are pretty thin. The WiFi was advertised at 83mbps. I experienced intermittent connectivity and maximum speeds of 14mbps so I had to tether to my phone to have Skype calls. Probably not a big deal for some, but important to know if you work while you travel.
I'd classify this more as a private room in a hostel, as you are staying with strangers that you don't have control over or know anything about.
Decent option if you're on a budget in Dublin or not too worried about hostel-like accommodation. I've stayed at other units in Dublin at the same price point that were much more enjoyable, so I probably wouldn't stay here again.
