Fantastic stay at Caroline's home in the center (and I mean center!) of Paris. Caroline is kind, communicative (great english), and helpful. She was flexible with my delayed arrival and helped make me comfortable right away. I loved how central the home was. The room itself was a good and comfortable size for 1-2 people. The apt is 2 blocks from the metro, 1 block from a market, 4ish blocks from the Louvre....perfect for sightseeing.
One thing to note, and is true with most Parisian apts, is that there are a lot of stairs (4+ flights). If you have a lot of luggage, it may be tough to maneuver but otherwise, should be no problem!
Would 100% stay again!
