Lili responded very quickly every time, checking in on us, if everything is good, no negotiation on the price though :)
Her friend met us at the door right on time, beautiful old (in a good way) building with red carpets (!) on the stairs, tiny little elevator.
Heaters were not turned on, but when we did, it got warm pretty fast and was hot at night. So better ask for them in advance and turn it down during the night.
Shower was hot but didn't last enough for us to take a bath sadly.
Pretty quite inside but not totally silent, could hear since voices from outside and from the inner garden, didn't bother enough though, slept well.
The apartment is pretty cozy with a lot of different small figures, flowers, candles and everything. Bed is enough for two average people probably (we are both 1.7 m), but not king size for sure, so if you're 1.9 m and big, should take into consideration.
There is a kitchen with everything needed, decorative fireplace with a couch to sit down and relax.
Overall liked the place, small subjective cons didn't bother, would recommend staying : )
Oh, almost forgot, location is amazing, near the park Luxembourg, dead center, 10-15 min to Louvre and Pompidou, 10 min to Pantheon and Latin quarters.
