My stay was wondeful.
It is a cozy tiny flat, perfect for two people having even a week-long trip, where you can find any detail that you need (shower, fridge, kitchenware, handy outlets, microwave, bed essentials, towels etc.)
Location is really cool, 10 min walk from Arc de Triomphe and metro station from where you can quickly go to almost any remarkable place in Paris in short time.
6th floor maybe challenging to reach three times per day, but it is a good routine to burn all the croissants eaten through the day.
Perfect check in and check out experience, nevertheless, it still would be great to check in earlier.
It would be nice if the host included a hair dryer rather than styler.
