We absolutely loved Sandrine's flat. The location is incredible. Just a few steps from Notre Dame, the metros, and tons of restaurants. If you decide to cook in, there is a surprisingly large grocery store on the first floor. It had everything we needed for our daily breakfast.
If you are a coffee drinker, there is a nespresso machine. The kitchen is very nice and had all we needed.
The sleeping arrangements worked well for our party of 5. My wife and I took the bedroom. Two kids took the sofa bed, and my youngest took the loft above the bedroom. I probably wouldnt suggest the loft for amorous adults as you can hear everything in the bedroom.
There is a washer dryer in the flat. The washer worked great but we could never figure out the dryer which was in French. We just hung our clothes and let them air dry.
We will stay here again without a doubt.
