We had a fantastic stay at Guillaume's apartment. The apartment was even more spacious than the photos implied, and there is a lovely view out the front room and a peaceful courtyard behind the kitchen and back bedroom. We were a family of 5 with a teenager and a 20 year old, and found plenty of room for everyone. There are actually two separate showers and two separate bathrooms, which was also a plus. The location could not be more perfect - we were able to walk to everything (Le Jardin Luxembourg, Notre Dame and Isle de Cite, Louvre, Tour Eiffel, etc). It is also very close to several Metro stops that can take you anywhere you want to go in the city. Guillaume was a gracious host and was waiting for us when we arrived. He gave us very clear directions to the apartment which we found no problem, and checked in on us to see how our stay was going. The only downside to the apartment is the noise (and only reason for 4 not 5 stars) - we were there during a hot week and needed to leave the windows open. The noise from the street is quite loud, and delivery trucks arrive very early in the morning. With the windows closed however the noise is muffled considerably, and the pros of the apartment outweighed the cons. Would highly recommend!
