If you are still looking for a place to stay in Paris, and this is available, book Emmanuel's now! The location is THE BEST in the whole city. It's right at Rue Montorgueil - a street full of wonderful bakeries and cafes, & u get to experience Paris the 'Parisian way'.
The place is very near to Chatelet-Les Halles (a big mall & train hub) only 7-8mins away (very walkable). From Chatelet-Les Halles, you can basically take the train to anywhere in Paris. Or you can just walk- we walked to Louvre etc. Supermarkets are nearby too - which is very handy for us travelling with a kid (big supermarket at the mall), and don't forget the recommended bakery just downstairs(brownies & cupcakes to die for)! and the cafes (Sthorer is right around the corner).
Emmanuel is the best host, he's very accommodating, and responsive. We met him on the first day, he's very friendly and nice and gave us a lot of tips on exploring Paris. He left us with maps, and restaurant recommendations too.
The flat might be just a little bit small (although I think this is standard Paris size) - but it worked well for 3 of us (me,husbn,and 5yo). Very clean, and practical. Beds are comfortable, all utilities worked well - kitchen/ bathroom (nice shower) and there's even a washing/dryer unit. Only thing to note might be the very short climb of stairs (the place is on 2nd fl) - but this doesn't bother us at all even with 2 big luggages.,nothing to worry about.
All in all, Emmanuel's place is a gem, you will not regret booking this! Highly recommended. We hope to come again and stay here. Thank you Emmanuel :)
