Stephane's place is light and airy and larger than we were expecting, even with the bed pulled down. The bed was larger than most European mattresses and was comfortable. We had perfect weather in Paris and thus never had an issue with the temperature in the apartment. Bathroom and shower were both roomy, although I did forget a couple times that the toilet was at the front of the apartment! Apartment was in a great location - 5 minutes from Notre Dame and 3 metro/RER/bus stops. We also loved walking everywhere and most sites were close enough. Longest walk from apartment was about 50 minutes to Eiffel Tower (could have been about half the time if took metro).
The best part of the airbnb by far was Stephane's 10-minute tour of the neighborhood. Such a generous use of his time and it really helped us make great restaurant choices during our stay!
