Pros: Good value. I have been to a couple of hostels, and this had the most variety for breakfast options and the most spacious common room. Big storage under the bed that can fit a suitcase (which you can also lock with your own or buy one from them). Every bed had own outlets and mini lights. You can leave your luggage until 8 pm. A great location for night life.
Cons: As the description says, it gets loud until late in the night (the downside of being so close to nightlife scene). And they mean it. In the first floor room, you can almost feel the bass's vibration like you are right on top of a club (maybe it actually is). And maybe I was just unlucky, but the room smelled so bad when I first walked in. (It was much better when I returned at night and common spaces were fine).
Not exactly sure on shower situation as I did not use it.
Overall, a good option for budget travelers.
