Support is extremely time consuming and delayed. We called their phone numbers multiple times and nobody picked up.
We sent messages in chat, and after 20 minutes (!!! we have literally arrived from the airport, 4 people with luggages in the street, and nobody even answers!), a support agent asks what is your booking ID! Dude why have I logged in if you need my booking ID? Can't you take a look at my profile? Why are you such an inconvenience?
Anyway, not getting any service we initially asked for, we had our check-in time at 4pm, where we stumbled upon a super dirty apartment and a worker who was cleaning the apartment, who asked for an extra 2 hours to get it ready!! Imagine being super tired, with elderly travellers and facing such a situation on your entry to Paris!
Anyway, going away from the super bad support/check-in experience, the apartment is just about fine, it's super old, squeaky on the floor and generally dirty to a point we didn't let our cloths touch the floors/cabinets/wardrobes, and converted one of the beds (which had clean/changed linens) to a luggage holder place, I guess we were lucky we were 4 rather than 6 here.
Other than these, the rest is fine, the apartment works as a place to stay and is super central so that's a large plus.
