What an amazing stay, if only for one night. Diane's entire house is wonderful and the small seperate room right at the top of the building provides enough space and a view of Paris only two or three steps from your bed.
Diane herself is a great host (nice chat, tour of the house, helpful in pointing out how to get around in town) and very easy going.
Add to all this the great location of her place (also next door to a metro stop) and it must be clear that I'd recommend it to anyone!
