We had a great experience staying at Alexis' place and he was the perfect host. Booking the apartment and communication before our arrival was super smooth. Alexis always replied quickly to all messages.
Upon our arrival, he greeted us at the apartment and gave us a tour, demonstrating how everything worked. There's also a full appendix with guides to everything in the apartment.
The apartment itself is super clean and modern with a hotel-like feel and looks exactly like in the pictures. It's very light and airy with a magnificent view thanks to being on the top floor of the building. It also has two little balconies, one of which has a table and two chairs. Staying here can almost be compared with staying in a hotel (less the daily cleaning-/turndown-/room service), except maybe even better as it has everything you could possibly need, including a steam oven (for those who prefers home cooking), washing machine/dryer, espresso machine, soda streamer, a printer and lots more. Wifi was fast and worked perfectly.
The apartment is very centrally located, with the Louvre just across the street and lots of restaurant shops and other services (such as Colette and Hotel Costes) within close walking distance. We stuck to walking and taxis but there seems to be lots of public transportation on the street just outside the apartment.
For such a busy street it's also worth mentioning that the apartment is nice and quiet at night and we didn't hear the neighbors once.
Alexis himself is super friendly and helpful. He'd even filled the fridge with water and drinks for us before our arrival.
All in all, we had a great experience and I'd highly recommend this place to anybody looking for a nice, clean, comfortable and central apartment in Paris. I would happily come back to stay here again. Thanks Alexis!
