Béatrice's home is in a GREAT location: literally minutes away from the Grand Palace and all of the sites, but just enough outside the city center that you can have a quiet evening and enjoy time with locals. Her home is also only 5 minutes walk from shopping and restaurants. The rooms are clean, modern, with ample amounts of natural light. There is access to a lovely patio from both rooms through super cool doors that can also be opened as windows. Béatrice is a great host and supplies you with all of the maps you need and has great suggestions if you either want to enjoy the busy city center or have a quiet night in the neighborhood.
Please note that the apartment doesn't have a kitchen etc (as described in her post), but you are so close to many cute cafes that have a lower price point than ones in city center. Also, she shares the building with 1 other resident so we were very cognizant of our noise level when entering the building (I was traveling with children), in order to keep good neighborly relations :-)
I highly recommend Béatrice's home and hope to be back soon, if she will have me!
PS: Audrey Hepburn's birthplace is also just a few blocks away so, added bonus!
