Olivier's place is spacious, light, clean and comfortable. Love the high ceilings! The kitchen and bathroom seem quite new and have everything you need - including, of course, plenty of wine glasses :) The beds are also very comfortable. The only (small) downside is that one of the bedrooms can only be accessed through the bathroom, so some coordination is required to prevent locking up your roommates in their bedroom.
The location is perfect and just a 10 minute walk away from the old center. The square right next door, around the Saint-Michel basilique, is very lively with plenty of good restaurants and bars and very close to the Capucins market where you can find the best oysters.
Communicating with Olivier was quick and (with the help of Google translate :)) clear. Our delayed arrival was no problem as we could check ourselves in. Instructions for checking out were also clear.
Would definitely recommend!
