Katy's flat has a lovely ambience. The main bedroom is located behind the kitchen/living area. The window wall in the bedroom is on the road side of the building. It can get warm in the flat. There are two small windows that open. One in the bedroom and one in the bathroom. We were 4 adults in the flat. Compared to other places we stayed at before it felt like a roomy flat. Yet, there is not much space to be by yourself (but who needs that in Paris, when you'll be out most of the time anyway).
