I needed housing in Paris at very short notice (one day for the day after) and really appreciated Kylliki's quick answer. She was able to have the apt cleaned and ready for us the next morning, and was very friendly and clear about everything so I found the place easily.
Only criticism is that it is very hot in there in the summer, I was there in july and at that time of the year AC would really be needed in that type of "under the roof" apartment.
Also the bed on the mezzanine is very confortable, but the sofa bed underneath is really hard.
Other than that the location is perfect, a very nice neighborhood.
The place is very cute, very nicely decorated, and very sunny and light.
