The very old building is not insulated, both thermal and acoustic, meaning that you can hear neighbours walking (or snoring at night).
The kitchen hood was not (has never been) cleaned and was spreading a disgusting smell of cigaret in the appartement.
We actually had the kitchen hood turned on to ventilate the musty smell coming from the bathroom and the kitchen.
Don't expect a pleasant showering experience.
The appartement is pretty tiny. No room to sit or work.
For all these inconveniences, I left after the 1st night and booked a very nice hotel for almost the same price (114€/night)…
