We spent an entire month at Adrien's apartment on rue Oberkampf in the 11th Arondissement. It's a compact, liveable, very modern one-bedroom with large bathroom and well-equipped kitchen. Everything is brand-new, with an induction cooktop, combination oven-microwave, good-sized refrigerator, dishwasher, and washing machine.
TV and internet worked great. Very strong WiFi. We streamed programs on Netflix and Prime and never had a problem.
The location is terrific, near lots of good restaurants and food stores (take Oberkampf to the east for a plethora of butchers, bakers, produce markets, etc.) and the Metro.
The only negative is that the apartment is on the ground floor and next to a shipping company with trucks loading and unloading goods right next to the apartment. This created some noise at times, but the electric shutters on the windows helped. Street noise is a fact of life in most big-city apartments, so we did not find the noise a major problem.
Adrien was a great host!
