We absolutely enjoyed our stay at Guillaume's apartment. It is in a very lively and diverse neighborhood in the Center of Paris with a wide variety of restaurants and bars. It's close to public transportation and the major attractions are just a few minutes cab or less than 20min bus ride away.
The entire apartment has a lot of natural light thanks to the wall to wall windows and balcony overlooking the streets. It is romantic and very Parisian.
Guillaume was very hospitable and shared lots of insight with us. We couldn't have asked for a better host.
