Our arrival was easy and we didn’t had any problems checking in. Chacha was also really friendly to let us check in earlier.
If your looking just for a place to sleep at night then this is perfect for you. It has an incredible location and many sights are in walking distance. I would defenitely book it again.
For the apartment; it is, what you would expect from Paris. It’s a small apartment, the walls are thin so I suggest bringing ear plugs when your sensitive for noises and you shouldn’t expect luxurious things, but it was clean and all necessities were there. Towels were provided.
