Overall, Vittorio has been super helpful and accommodating.
However, we visited during a particularly hot period in Paris and if you decide to book it, then be aware that the air moistener for the plants in the guest room makes that the temperature in the room feels about 10 degrees warmer than outside or the rest of the apartment. So, we just had to open the windows - even though Vittorio warned us about mosquitos. But it was just too hot and so over nights the mosquitos had a feast with us. It was just hard to get a good night sleep this way.
Other than that it’s a great apartment, with very nice touches, great art/ photography, comfy feeling and a super nice and flexible host.
