I was here in summer 2018. Please be warned: this hostel is under the roof of a multistore building. When the weather is very warm, as it was when I visited Poznan, it is unbearable to stay in the rooms! Moreover: it's four floors up, carrying your luggage on the stairs. And I couldn't even open the window at night, because of the noise of the street. There is a banking automat right underneath, so it's beeps (and noise of bars) all night long. And on top: my 1 person bedroom was next to the living room, where everyone can sit and in the morning have breakfast too.
Apart from that: the atmosphere was rather depressing, guests were not open for contact. It felt more like a family pension, not like a hostel. And the place did not feel very clean, also due to the carpet (alert for travellers with allergies!).
To be short: I looked for (and found) a nice little airbnb instead, because of the heat and the noise. Maybe the place is perfect for party people who don't sleep a lot, but not for me anyway.
