Antoine's place is a lovely and very well maintained studio in a vibrant area that lives 24 hours a day. The Beleville station is 2 minutes away, and the metro will take you to the main tourist attractions in up to 20 minutes. Everything you need for your stay is within 5 minutes walking distance: an excellent bakery is just across the street, the markets are a couple of buildings away, and there are lots of fast food restaurants of all kind. We've ran into the open street market set on Tuesday morning, but it was the day of our departure so we were already on the way to the airport.
The studio is backyard oriented, and the neighborhood is surprisingly quiet for the area. Someone had planted the bamboo trees, so you'll enjoy the mini rainforest environment on the small private terrace in thr middle of Parials.
No wifi is available, so make sure you have your own internet (not a problem, and very affordable in France).
