I stayed at Elsa's place for 8 nights and was very comfortable. Bed was super comfy, and the shower was hot with great water pressure (A must for me lol). I had no trouble sleeping at night (I do sleep with earplugs tho).
The location is excellent - easy walking distance to the Eiffel Tower and Museums. There were even a set of small dumbbells - perfect for a traveling fitness model :)
