Elise’s apartment is in the best area in Paris, the streets are beautiful and close to the Luxembourg gardens, with easy access to Notre dame, the louvre, and many appealing restaurants and cafes. It is clean and felt very safe (you have to open the outside with a code and the actual unit is up one flight of stairs). It has everything you need for a short stay in paris — a stand in shower and a decent bed. We loved the streets when we walked out the door every morning.
Be aware, it is quite small apartment that can fit maximum 2 people who are comfortable squeezing into tight spaces, but this is Paris and you don’t want to be inside for long anyway. Those with heavy luggage should know there is no lift and the 1 flight of stairs are a bit narrow and aren’t lit in the night - we used our phone flashlight and had no problems but definitely worth noting for anyone with mobility issues. Elise was a good host - she helped us when we had a question during our check-in very quickly and messaged us throughout our stay to make sure everything was going well.
Overall, I highly recommend this apartment, it is a great area for a great price, and a functional apartment - all you need for a great Paris trip!
