Stop looking; this is the one.
The space is perfect for a couple. It's got everything you need and then some. Alexandre is excellent. Ask, and it'll get done.. but truthfully he thought thru everything ahead of time. Location is fabulous. Convenient to the metro and several solid food options. See the Eiffel tower every night.
The only potential downside: the elevator is tiny-- but it still has an elevator!
Do yourself a favor and book this one before someone else does.
