The apartment is nice and cosy. It is spacious and has everything you need. It does get abit stuffy but there is a fan provided.
As for check in, Filippo did let me know in advance that he won't be around but there would be someone helping out. And everything worked out fine, it was smooth.
It is quite a convenient location as well. All in all, I'm pretty happy with this apartment. I would recommend it to my friends, if they go to Paris.
