Daniel's place is perfect for two people. The place is really tiny but perfect for two. If you're too tall or broad shouldered, it might be very tight. Something to keep in mind!
The biggest pluses of this place is that it is very quiet (we are light sleepers so quiet is important), clean (we are clean freaks), near really good restaurants (eg., Pierre Sang, Ober mama), close to metro or to walk to many places, and had a market very close by. I like how Daniel has thought of a lot of the small things that make a stay more comfortable. This includes ample bath towels, ample toilet paper/paper towels, an umbrella (Paris weather can be unpredictable), and welcome water/coke/milk.
We met with James for check-in and he was very kind and helpful explaining everything to us. Daniel met us during check out and even offered to help carry our luggage down. A nice gesture!
We loved our stay and will definitely try to stay here during our next stay in Paris!
