My mum and I had a great stay at Yann's place. The area is so close to many places of interest and you can easier walk to them. It also has lots of sweet streets running off it so you don't need to walk far for food/drink. There's a metro round the corner too if you need to use that instead.
The flat itself is lovely and so quiet at night; such a joy as I live in London! We had everything we needed for our five days there. Decent coffee machine which Yann gave us a box of capsules for, all mod cons to make food etc. The place was sparkling clean when we got there and all rooms were a good size. The bathroom has a nice big shower with very good water pressure (essential!).
If we needed anything Yann responded very quickly. I'd highly recommend staying here especially if it's your first time in Paris, the location is great!
