We enjoyed our stay at the flat. It is on a third floor walk-up (for those sensitive to stairs); however I've come to appreciate walk-ups since living in NYC! It also has just one shower and one toilet, and they're separate (which is handy).
The flat was clean and the appliances were easy to use. It also got great light during the day!
Check-in and check-out were easy and the host was responsive if we needed anything.
I loved being a leisurely walk from some of my favorite Parisian neighborhoods.
I look forward to staying again!
