Boris was very accommodating and easy to communicate with. We never met him, but he emailed and sent text messages to helps us get started. The best thing about the unit is its location. The Island is very safe and has excellent food choices very close. Metro stops, sight seeing and parks are all right there. The unit is small and the pull out bed is not the most luxurious- but we slept well and it was a great home base for our adventures in Paris.
