A+! Stayed here in mid-August 2021 (a quieter time in Paris albeit still bustling at some spots) and the area is PERFECT. It's in the 2nd arrondissement / Sentier area which is super hip and local (not many tourists which was great). Could walk to some cool restaurants / cafes like Echo, Tigermilk, Caminito, etc. So many great spots around that didn't feel like tourist traps. Frenchie and Frenchie To Go are also super close and yummy/popular. Plenty of markets nearby too.
The studio itself is in between a couple clothing stores and up a few flights of stairs (no elevator FYI but that was OK since I only had a backpack and carry on). It was very quiet which was nice and had everything I needed - a small fridge, stove, sink, some dishes and glassware, utensils, etc. A small table with stools and a TV (I'll be honest I never used the TV). The bathroom/shower were great - shower had great water pressure (rain-like faucet overhead and a hand-held as well). Bed was perfect size and comfortable. Great and cute touches to the studio like the lighting, antlers, etc. The air conditioning unit worked really well and the room always felt perfectly cool (a variety of settings). It's a perfect place to stay alone and I would definitely stay there again. Owners were very responsive and helpful through the Airbnb app whenever I had questions! The Wifi was super easy and strong for my phone(s) and internet/streaming shows on my apps, etc. Never had issues with the Wifi feeling slow.
One note is the stairway/entry way at night doesn't have lighting so use your phone flashlight to walk in and up (there was a sensor light when I got to my door); was not a problem at all but just FYI.
Merci!
