Sorry didn't note second part of your request.. yes. .I consider Parisbestlodge to be extremely reliable.. I have been on the forums for at least ten years now, this forum , Tripadvisor.com, Fodars, etc.. and I have never heard a bad thing about them. I used them after always getting hotel rooms( I still prefer hotels for shorter stays.. I like maid making my bed and changing my towels daily, lol ) .. after reading so many glowing reviews. They are not luxury apartments, but clean, EXACTLY as pictured and well eqquiped and kept..
I met the owner and he showed me two other apartments while we were there ( in between rentals in the same building as ours) and we also befriended a lady renting one of his other apartments and she let us view her rooms.
The deposit is civilized.
Thierry ( who manages the business and owns some of the apartments) speaks and writes perfect english and is a lovely man.
However.. downside.. is at this point his apartments may be snapped up,, many book year after year by folks who know. We couldn't get the apartment we had last time so he suggested another unit this year.. it looks lovely. Small, but lovely !
good luck.
