NEGATIVES: The place had all amenities provided but linen and towels weren't clean. In reality it doesn't look as good as in the pictures.
The flat feels and looks like a converted basement. It's a dark grim place. Smells of mould and it's not pleasant to sleep in. In fact there's visible mould in the bathroom. And I think the smell comes from the ceiling (some old bricks).
It's also very loud from the street - e.g. motorcycles all night or very loud bin collection at 1AM. Almost impossible to sleep without ear plugs.
POSITIVES: The only positive thing about this place is location and communication with host whose notes where very helpful. Very good check-in experience. Key in a locker by the window is a great idea.
