Although I was well aware of the appartement's size from reading the previous reviews, I was still quite surprised how small it was. Since the shower, kitchen counter ,sink and shower are all packed in a 15 sq.m. room, it made the usage quite impractical. The toillet is situated in a hallway as described, which for me was a good thing from a hygienic point of view.
Other thing we noticed immediately is how stuffy and hot the room was comparing to the hallway and nice outdoor temperature (22-25°C). Only source of fresh air is the small roof window which wasn't enough to air the room. If it weren't for the eletric fan in the room, I think it would be unbearable to spend a longer amount of time inside. Since we only spent nights there,it was managable.
We also had a problem with folding the bed. Although we received a video with many detailed instructions, it was still really hard to fold it, it took us several tries.
Studio itself is clean, well equipped, there were towels also which was a nice touch. Unfortunately we couldn't use the coffee machine since there were no capsules,but Anne apologized and informed us about nearby Nespresso shop.
The really good thing about the studio was the location, literally right next to Champs Elysees. Price was amazing for that kind of location so I am happy we managed to stay there. I would reccomend this appartement if you are not planning to spend lot of time inside, and if the temperatures outdoors are not high. It is perfect for sightseeing since a lot of main attractions are walking distance away.
