Nathalie’s place is a great option. It was my first time in Paris and I found the loft very conveniently located (close to public transportation and restaurants/cafes/pubs/markets).
The apartment is comfortable, clean and colorful. It has a pretty terrace. And it has all the amenities you need for a nice stay.
Last but not least, Nathalie and Joan are very welcoming, helpful, and flexible with check in and check out.
I would gladly come back!
