Federico was really nice and friendly, he directly helped us to get our luggage up to the third floor.
He even gave us really nice tips on restaurants and things we should visit.
The apartment is really close to a supermarket (about 5 minutes) and you can easily walk to the louvre (about 20-30 minutes) and other sights from there.
There even is a bus station almost in front of the apartment and the metro is close too.
All in all, the apartment was really cosy and beautiful and we enjoyed staying there.
