Carole was such a wonderful hostess. She was there to greet us at the apartment and was very communicative the whole time we were there. Myy daughter's luggage was delayed a day and a half from the airline. She offered to see if any clothes at her house would work to borrow (though we used the excuse to shop instead!). Also, she helped us coordinate delivery of the luggage and arranged to be available to accept the luggage so we did not have to schedule our day around that. She gave us suggestions on where to go, how to get there, etc. So, so kind and helpful. Anything we needed, or questions we had, she answered or addressed right away.
The location is great. Restaurants and grocery all nearby. Two (short) blocks from the metro line. 10 minute or less walk to Marchee d'Enfantes Rouge. 25-30 minute walk to Notre Dame (or maybe 40 if you stroll like us and stop for patisserie!). You could even walk to the Louvre...farther away, but flat, and Rivoli has good shopping.
Apartment had everything we needed, including plenty of toilet paper, which I have found to not typically be true of AirBnBs in Europe. On demand hot water heater so we could all shower. We were there in cold weather, and the apartment was warm and beds comfortable.
If you have a difficult time with stairs, there are 3 flights to the apartment and all the bedrooms are upstairs once you get to the apartment. This is fully disclosed, and were not a problem for us.
Quit looking, and book this place. That's what we did after reading only a few reviews, and it was a great decision!
