We had a fantastic stay at Katia's place and would highly recommend. The apartment is an excellent size, and beautifully furnished. It really feels like home! Location is really excellent. Short walk to Notre dame or the louvre, slightly longer walk (20-25 min) to musee d'orsee. Right in the middle of an excellent restaurant/pub district so of course it can be a little noisy at night, but we downloaded a background noise app on my phone and had five excellent nights sleep. We were sad to leave.
