Hélène is a very nice host who offers you everything you need during the stay. I forgot to bring my convertor and she offered me one which was of great help.
The location of apartment is convenient where both metro and RER stations are within 7 mins walk. One thing I extremely love about is the restaurants within the neighbourhood. I recommend Les Cocottes and Pottoka. I am starting to miss the great food there.
If you are travelling alone, Hélène's list is definitely a good choice.
