We saw Raphaella when we came and left. She showed us everything we needed and gave some usefull info. She was very cultured and correct with us and didn't disturb us for the time we lived there. The deposit of 500 euro was unfrosen in 2 days that means the hostess is very honest with her guests if they are honest with her. So if you left everything as it was before you defenetly should not worry about refunding of your deposit :)
Very spacious appartment for 4 persons but even 6 can stay here with comfort cause 2 sofas in the living room look comfortable enough for sleeping. It's not very modern and reinnovated but defenetly clean and free of personal belongings.
Saint Mande district looks very safe (for 4 days we did not see any annoying or criminal-like persons there) and pleasant for walking: Vensain forest with 2 lakes, beautiful Vensain Castle, Floral park of Paris and the Zoo (but the last one was closed in November) are all in the footwalk distance. About 1,3 km till 2 metro stations (2 different lines) by feet or by bus 86 to Saint Mande metro.
Raphaella, thank you for memorable parisienn days which wouldn't be so nice without your appartment. I wish to stay there again.
