My husband and I stayed at Felipe's apartment which happens to be in my favourite neighbourhood in Paris. The location was perfect because it was almost exactly beside the Chatelet -Les Halles station which is SO convenient to get off the RER and be almost at your doorstep after planes/trains/etc.
It's also awesome because you're central to EVERYTHING.
You can walk to the Eiffel Tower in 50 minutes, 15 minutes (max) to the islands (Notre Dame, Ile St-Louis), the Marais has everything you could want for amazing boulangeries, cafés, shopping (HELLO THERE IS A UNIQLO AND LIKE A BILLION ELEVEN PARIS SHOPS), fine dining (I'll recommend L'Ange 20 in the Marais right now, and Mon Vieil Ami on Ile St-Louis).
Basically the apartment was a fab spot to have as "home" while in Paris. Clean, cozy and some say small (but who needs more space??? Hello you're in Paris- GET OUT), comfortable bed, awesome shower with cool temperature thing, quiet and just well appointed in general. OH! And the Monop' is right next door so you've got groceries available until midnight.
I read some reviews about the neighbourhood's sex shops, but they aren't exactly the type of people you should be worried about- those guys and gals are more afraid of you than you are of them! Seriously. I went out alone without my husband (small blonde with a big purse and a guide book...Shouldn't I be worried?) and never once was apprehensive. Plus it's fun to look in ;)
OK! So THAT about wraps up. Felipe was AWESOME, communication was always responded to ASAP prior to our stay, he was accommodating, helpful, kind. We didn't need to contact him while there because everything was perfect, though he checked in just to be sure, which was also just great.
STAY HERE! You won't regret it!
