We appreciated a lot the availability to bring us the keys on our arrival and the explanation of how everything worked inside the apartment. The hot water and the heating worked very well.
Nevertheless, it was not a pleasant and resting stay. Sadly, the apartment was not very clean: powder on the objects and shelves, dirty walls, old broken pillows, grey spots on the bed sheets, very old towels. We spent the first hours of our stay buying product to disinfect and washing everything.
Moreover, the sofa-bed was very uncomfortable and the position on the entrance hall of the building made impossibile to rest properly (people coming out and shouting just outside the old fragile door, the light turning on, the noisy cleaning in the morning...).
I get that the price is low, but some major restoration and rethinking of the apartment should be taken before it can be appropriate for a pleasant stay by other guests.
Until that moment, don't fall in the trap unless you want your holiday ruined.
