I didn't met presently Antonella, but in time to time she entered in contact just to check if everything was ok. Her son, was my host: no problems there. My stay was very good.
For independent travellers, this place is for you: very central; supermarket at BLV Cappuccines or in line 8 - Militaire School; bus or metro just on the corner; a bakery across the street (good coffee). My daily living in the apartment was smooth.
Regarding the young host Stefan, very cordially, low profile and we hardly stumble in each other.
