This flat is a small but very efficient, clean space in a quiet neighborhood in an extremely convenient location (walking distance to almost everything and the Metro was very easy to use).
Bed was just a thin mattress on plywood but was astonishingly comfortable.
No air conditioning, but the fan was quite adequate in the August heat.
Flat had a washer/drier combo machine which was invaluable since our luggage got lost by the airline.
Rumi, the hostess, was AMAZINGLY helpful: gave us great restaurant recommendations, was extremely responsive to questions and saved the day by accepting our lost luggage from the airline delivery company while we were across town at the Louvre.
It was everything we needed for a great 5 day trip to Paris.
Strongly recommend the Paris Pass, too!
