I stayed 3 nights with Florence and her husband and children and it was wonderful! Super close to the Eiffel tower and metro station; within walking distance to other major sites too.
If you're looking for a hotel then book elsewhere ; they are as much your hosts as you are their guest and the experience was that of a typical Parisian home - very cosy and just lovely. The advice and recommendations I received were invaluable and there was nothing that was too much trouble. They were very attentive and made sure my stay was just perfect. Great communication with Florence before and after my stay too.
Just be aware there are a few rules not listed on the site: bathroom/shower use from 7.30am to 10pm only (respect for neighbours) ; WiFi is turned off generally during those times too. Also the door to the guest bedroom is semi opaque which wasn't really an issue for me but it's worth noting.
All in all an excellent stay in Paris and I would highly recommend!
