We had a great stay at Katy and Vincent's place. The house is sparkling clean and very comfortable. Everything is intuitively where you'd expect it to be. The location is fantastic, close walk to many metro stations and centrally connected.
Katy is the most caring and wonderful host ever! During our stay in Paris I fell and hurt my ankle. Katy went out of her way to help me.
Communication with Vincent was always promptly answered.
I would highly recommend their place for a stay in Paris.
