My wife and I overall enjoyed our stay. The location is very convenient and is near many restaurants and public transportation. The kitchen was stocked with pots, pans, and a mini fridge for easy cooking. Shower has good pressure and the unit was very clean.
On the other hand, it is a bit small.. as many of the flats are in Paris. I wouldn’t recommend more than 2 people. The bedroom portion also has a very very low ceiling that made it a bit hard to get in and out of bed. I am 5’0 and my wife is 5’4 and we still had to duck. You are also on the first floor so it can get very noisy at night during the weekend (train is right below and many bars are within a close proximity).
