We had a great stay in Paris at Michel's place. It's very central with a great view, and easy access to the metro, taxis, and all the central attractions. Definitely recommended.
There is an interesting unusual decor and a spacious living room, good bed, good AC, good pressure/hot water in the shower and good towels (very important). All the essentials are in the kitchen.
Check-in and out is very easy, and Michel is very responsive, getting back to us immediately on 2-3 questions we had through the week. There is great light with the curtains open and you can shut it all out to sleep late if you want. The street outside is not loud but there is a cafe that is open late so we kept windows closed at night.
The lift might be an problem for those who have difficulty climbing stairs or carrying heavy luggage. It's located half a flight up from the ground floor, within the staircase, and stops half a flight above the apartment. It was not an issue for us. We felt secure in the apartment but a deadbolt lock would be an improvement.
We would stay at Michel's place again.
