I am french and i rent my entire flat for 5 to 20 nights. One of the most rated flat in the neighboorhood.
Nicely located, 7 minutes from the Tour Eiffel, Invalides (where is the huge Tombstone of Napoléon Bonaparte !).
Towels, shower gel, coffee and everything you need to feel like home.
The flat has one comfortable double bed and one sofa bed (same size as the bed), also very comfortable !
