We had a great stay at the appartment - the location just couldn't be better, in a quiet, small, but very central street - with short walking distance from many of the city attractions - we hardly needed to use the metro. Its also very close to the les halles train station, making it really easy to get from/to the airport and other areas more further away. The appartment is very clean and very well equipped, the kitchen has everything you need to cook and eat in after shopping in all the amazing bakeries, fruit and cheese shops around the house... Antoine was very responsive and helpful, the instructions were very clear, we really had no problems.
One thing some may find problematic is that the walls are really thin and sometimes you can hear the neighbors or people passing in the hallway... We did not bother that much, no one was having any loud parties, but i can see how some may be disturbed by that.
Still, I would gladly come again, we had a great time here.
