Alice and Vincent's place was great for our 6-day stay in Paris. The apartment is exceptionally quiet and peaceful. It was also extremely secure. To access the unit, you needed a key for 2 doors, a key to access the stairs, or a code to use the elevator. And of course, there's a key for the unit. If security is important to you, this is a great spot.
The kitchen and living space were all very comfortable. The bedroom and bathroom have some drawbacks. There's not much bedside space to speak of. And the double bed was a bit small for my wife and me. The bathroom is well-designed but the shower is high up, which was inconvenient for us and would be a problem for others.
The unit is about a 5-minute walk from the metro, close to plenty of shops and some restaurants.
Other than the bed size, there were no real issues with their place. We enjoyed the stay and Vincent was extremely nice and easy to communicate with. If you're an English speaker, this is a great spot to choose from.
