Can't beat the price. The check-in is very streamlined and efficient. The building is secure.
However, the walls are extremely thin. The ceiling fan was so noisy that I couldn't sleep with it on. The bed is not very comfortable. The room lock is flimsy and easily broken/picked if somebody wanted to access your space.
The recommendations for things to do was very nice. I'd avoid the laundry service, as it took over a day and half and is limited to 6 Euro for 3kg. There's a laundromat nearby that you can use.
