Maya is a really wonderful host, very communicative, open, friendly, and helpful! I asked her a few questions beforehand and she was always very responsive and gave great suggestions. The check-in process was very easy and everything went totally fine. The apartment is very small, for no more than 2 people, but the bathroom is a reasonable size and there is enough storage for everything. The WIFI works very well and the balcony is fabulous! It's also well laid out for such a small apartment. The Alésia area is very well connected via Metro and bus, and the neighborhood itself is also very nice to walk around and for shopping.
There were a few reasons as to why I didn't give the studio 5 stars. First, it was somewhat dirty. There was dirt, dust, and hair in multiple different places, including the inside the pulldown bed, on the balcony, and in the bathroom. In general it just wasn't very clean. Not horribly bad but also definitely not clean. This only bugged us slightly as we are not so picky, but I could imagine others wouldn't react that way. Second, there was also occasionally a weird smell from the bathroom, most likely from the pipes or other bathrooms surrounding it. We closed the door and luckily it didn't happen too much. Thirdly, the kitchen wasn't very well equipped, with only one or two larger mugs and no sharp knives for cutting. All somewhat smaller things but together they did take away that last star for us.
