Pros - excellent location, nice flat, good building with code security and elevator. Walking distance to the metros and even some nightlife, cafes, and supermarket for grocery shopping.
Cons - poor communication. I received communication regarding check-in the day of (and only after I inquired about it!). I was so nervous that I wouldn't receive a response and I ended up spending money on another hotel room in case the apartment manager (not the host) never responded. No early check-in (which is OK!), but apartment was not cleaned correctly (especially considering post-covid conditions). Couch could use a serious deep clean (or replacement) as it reaked. No toiletries were provided, so I had to purchase some in a nearby monoprix. TV did not work (asked apartment manager about it and never received a response).
If you just need a quick place to stay in an excellent location and are OK with things being not as sanitary, then this is an OK place to stay.
