Elisabeth's flat is just lovely: excellent location, quiet, clean, and with excellent amenities. There was plenty of hot water and the water pressure was fantastic. The WiFi was super-fast and consistent. There is even a washing machine in the bathroom (excellent for longer stays!). And the bed was extremely comfy! The neighbours, too, were very pleasant.
I did not meet Elisabeth (a friend of hers promptly checked me in), but Elisabeth was very responsive and helpful. Everything you might need is just outside the door of the building: a grocery store, world-class pastry, ATM maching, Metro stop - all within a half block.
I am so glad I was able to stay at Elisabeth's appartement, and hope to stay again when I return to Paris! Merci beaucoup, Elisabeth - tout était super!! :)
