Flat is perfectly located, in a very vivid area. Being part of a passage though, you cannot hear any noises from the main street - perfect.
The flat looks exactly as described and shown in the pictures. The rooms in the cellar do have a lot of charm due to the brickstone optic and the warm light. Great compliment to what you made out of this location - Very comfy.
Only negative comments: yes, there is a smell of moist, typical for a cellar, although we couldn't detect any yeast. I think it is unavoidable considering that the sleeping rooms and bathroom don't have windows. We spent most of our time discovering Paris anyway and got quickly used to the smell.
Generally speaking, the rooms could have been cleaned a bit more thoroughly, there were finger prints on the mirror and on the walls of the toilet and shower room. A bit more cleaning in the corners (dust) and of the carpets (ribbons, coins) would have been appreciated.
Overall, a great location with lots of charm, great value for money, I would definitely book this flat again. Thank you for having us :)
