We had a great time staying at William's place. It was very clean and situated in a convenient location, next to the Saint Paul metro. There are several great restaurants and bars within walking distance, and it was very easy for us to take the metro to any of the major tourist locations. William was very flexible with our check-in and check-out times as well. We arrived quite late in the evening, but he waited for us regardless. We would love to stay at William's apartment again the next time we are in Paris.
