We really liked Pénélope's place.
I knew we'll like this place when I saw two pieces of chocolate and towels on the bed when we entered the room, lol!
Everything is well organized and clean. There are cutleries, plates and pans.
Location is great, if you need to take train from Gare de lyon, or like Bastille area. East mama (an Italian restaurant) is 5mins walk from the place. Strongly recommend to try it.
She gave very detailed instructions about the place and check-in.
The shower booth is small (less than 1 square meter). Even though a small shower seems to be common in Paris, you might want to avoid it if you are big (say above medium size).
The bed is very soft, so my back wasn't feeling good after one night of sleep.
