Phenomenal stay in Paris! Milena and her brother were fantastic hosts, super helpful and easy to communicate with. Milena even helped meet me to give me back an item I forgot when I left.
The apartment itself is perfect for 1-2 people. I was traveling solo and working remotely (the wifi is excellent 200+ mbps). I appreciated that the apartment had some small details that are just really useful when traveling. (Soaps, extra towels if needed, the kitchen was stocked with staples.) As far as noise, while you can hear noise from outside and above neighbors a bit, honestly I didn't think it was an issue (you're in Paris...I expect this in cities I guess).
Everything was incredibly clean. It's small (not too small) but feels cozy. Location is great. Right by Montmarte, Moulin Rouge, and the Pigalle Metro station. As a solo female traveler I felt very safe. I will definitely stay here again when I'm in Paris. Don't hesitate to book this apartment, highly recommend.
