The photos do not do this place justice. The flat is spacious, huge, clean. Furniture and beds are all comfortable and couches are especially cozy. Lots and lots of space for spreading out with all your gear.
We had 2 adult (couple), 2 adult friends, and a 7-month old baby and we had more than enough room.
Wifi was great, fast. We were also provided with a great guide with everything we needed to know about the area, about the flat, etc. Alexandre also provided a portable hotspot so we could connect to the internet while we were out and about! Great service.
There is a lift—but you probably won't use it day-to-day as its quite small. That said, finding a place with a lift in Paris is nearly impossible and it was a godsend to use for moving all our luggage up and schlep the baby, stroller, etc. We have an UPPABaby stroller + infant carseat attached and it didn't fit fully expanded because the elevator has a bit of a curve. Folding it slightly made it fit though.
Great experience. Super clean. Great service. HUGE flat. Would return again and highly recommend, absolutely.
