The apt is just as pictured - quaint, spacious for Paris, full of natural light. The location is also perfect - on a lively enclosed square w cafes/restaurants all around very close to 2-3 metro lines, many key sites (eg the Louvre) and some of the best boutiques in the city. Despite the location the apt is very quiet since it faces away from the square. It was a great location and space to stay in for a few days visiting Paris.
The only issues were that at the time we stayed towels were not included in the amenities so we had to buy our own (luckily there is a Monoprix around the corner) and the apt was a bit dusty - nothing you would notice in your own home but not the level of hotel-style cleanliness I would provide for a guest.
Lastly, Alexis was a great host - extremely easy to get in touch with, happy to give tips or answer questions if needed, and very prompt with his replies.
