Lovely stay! Perfect for a few days in Paris. The flat is well-located, very clean and had everything we needed for a short stay (you will need your own shampoo and body wash). Everything in Paris is small and expensive, so don't expect tons of space, but we found it perfectly adequate for a stay for two and the location can't be beat - less than 2 minutes walk to the Louvre and the Louvre-Rivoli train station. The hosts were amazing and very communicative, and Johanna was so patient when we arrived over an hour late for check-in due to traffic.
Note that the flat is up four flights of narrow stairs (again, common for Paris) so I would not recommend this for people with mobility issues or large bags. There is no AC (also common for Paris) and we visited during the crazy summer heat wave, but a powerful fan was provided and we found it comfortable with the windows open at night. If you are a light sleeper or sensitive to noise, light or heat you might want a hotel.
We will be back!
