We spent a very happy 5 days staying at Xavier's super loft apartment in the Marais. Xavier was very helpful, everything was as described, and worked very well. Xavier was very generous with regard to saying we could use the things in his kitchen, he had left towels for us ( I hadn't expected this), the arrangements for arrival and departure were really straightforward, and he gave us a quick tour and explanation when we got to the flat. He had left us really helpful information about local amenities and restaurants.
The location of his apartment is superb...we began to imagine ourselves as real Parisians!!
We would definitely return and can highly recommend.
