We were completely satisfied with the communication between Nathalie and ourselves. She always been helpful and supportive. Her relative, Daniel welcomed us and helped to unpack the car - despite the rain, which we very appreciated as our little son was sleeping when we arrived. The flat was clean and well equipped and we got some fruits and biscuits as welcome gift - very kind from them!!!
To make the long story short: actually we were (nearly) just sleeping in the flat but it was very comfortable.
There are some public transports near to the flat (bus 734, 735, tram 28E) and the blue line metro is about 8-9 min. walking - not a big deal. :-)
I have to mention that we asked Nathalie if we could stay a bit longer in the flat as our flight was late afternoon and our little son needed an afternoon rest... Nathalie was (could be) flexible, so thank you for that! :-)
