We are searching for reasonably priced housing in or near Neiully Sur Seine for sixteen university students in late April and May of 2012. Do you have suggestions, other than hostels, for beginning our search?
You might try www.virtualtourist.com, and type in Neiully sur Seine. Hotel Charlemagne is one listed, and it has other information about the area. I stayed in this area last year, in an apartment, and liked it a lot.
