Alexis' place is amazing! We stayed there for a weekend and we were 5 friends: the apartment is very spacious, clean and comfortable, there is everything you need (wifi works perfectly, there is a big tv, stoves, bathroom accessories,comfortable beds, and you can even buy wine bottles if you wish to) and there is also a mini guide of the apartment that helps a lot. The place is just in front of the Louvre, and from the balcony there's a great view. I highly recommend it especially if you are a small group of friends, since the price is totally fair.
Alexis is very helpful as well, I had a few question before our arrival and he always answered immediately.
We definitely will come back :)
