Location, location, location! Karine's place is in a great neighborhood with plenty around and lots to do. Unlike lots of Airbnbs these days, you really feel like you are staying in someone's HOME, which I personally love. The apartment is a little more rough around the edges than the pictures show (some water damage in the bathroom, peeling paint, etc.), but I think that is to be expected in buildings of this age and in Europe! So if you're expecting a pristine new build show home, this is not it, but if you want a homey apartment that feels like somewhere a real person would live, then I highly recommend Karine's house.
Karine was super responsive and easy to communicate with. She even left recommendations for where to eat and shop in the area.
Again, the location is FANTASTIC and easily walkable or a short bike ride to lots of the best Paris has to offer.
Highly recommend for price in the area!
