Building is located close to maint city center, in a wonderful park that we enjoyed a lot.
Employees are very kind and helpful. The shared living room is quiet and cosy.
But it was a bit too expensive for the room in my opinion. Beds were not made, we had no towel (you have to rent one for a price) we had no shower carpet, missing the main lightbulb in our room (they proposed to change room but we were already installed so we chose to stay). Noise isolation is non existent, take earplugs! Oh and the coffee is really expensive yet tasty. Wifi is great and works anywhere in the building.
As you can find youth hostels around 20€/night, I expected a little bit more from Generator. Knowing that it's a bit more expensive than the others ones and you have to pay for expected extras, I still recommand it but be aware of those tiny things!
