Our family of 4 (2 adults and 2 children ages 4 and 9) stayed at Sylvie's place. It was much better than the picture show - it is HUGE by Paris's standards, a really big one bedroom apartment. It is clean, nicely remodeled, has a balcony and a nicely equipped kitchen. The apartment has a bed in the bedroom (queen size) and a pull out couch (queen size) in a living room. Living room and a dining room are combined together and the foyer is very big. The apartment is on the 5th floor but thankfully, the building has an elevator as we had suitcases and a stroller with us.
Sylvie was out of town and could not meet us but her neighbor Jerome was a delight to deal with. Our train was delayed after it was struck by lighting and lost power. He waited for us and communicated with us the entire journey giving helpful tips from how to claim the train company, to which route to take to the apartment. In person he was even more pleasant and funny. He helped us with suitcases, explained everything and made us feel welcome.
On the way back our flight was canceled, he helped us get in touch with Sylvie. Sylvie responds to emails very quickly and communicates well. She was very willing to accommodate us and to extend our stay as she did not want us to be stranded in the city without a place to stay until our re-booked flight the following day.
She is a great host and has her apartment nicely set up for all guests.
