Helene's place shall be rated 6 stars, it is exceptional for many reasons: she is a terrific host (small details make a big difference), the apartment is amazing for Paris (family of 4, lots of space, nice furniture, all you need in the kitchen, super clean, view of the eiffel tower from the balcony), top neighborhood with everything close by (visits, transports, shops etc). We used to live in Paris many years ago and our stay at Helene's made us feel as being Parisians again. Do not hesitate, just book it!
