Kajsa and Fred were really excellent hosts. They were friendly, accommodating, and flexible. Communication was great, and they helped us with everything we needed during our stay. Their flat is AMAZING. Unless you have real physical limitations, do not be daunted by needing to walk up all the stairs - it is well worth the effort and you get used to the climb. The neighborhood is hands-down the best place to stay in Paris. Montmartre is close to the main attractions but a bit off to the side so it doesn't get crazy tourist traffic (except near Sacre Coeur and Place du Tertre). Every street has character, the food is amazing, the people-watching is top-notch. I really can't recommend it enough. I also want to mention that Kajsa and Fred are doing Airbnb like it's meant to be. It's not a flat that was bought by someone looking for a revenue opportunity and uses a management service to run it like a one-room hotel. It is their home. It has been for some time and it has all the touches that come with that. When I stayed, I really felt like I was staying with a friend and it was very comfortable in a different way than many other Airbnb properties you'll find. Thank you Kajsa and Fred for doing it right!!
