We stay at Kellys place 4 people (two adults and two kids) and everything was fantastic. The appartment is son clean and full of beautiful details, so cosy. The beds are comfortables and you stay there like in a real home.
The plece is in the Sorbonne square, very central position to explore Paris, even on foot and with public transport in the door. I will recomend this place, next time in Paris I will repeat for sure.
