To start with, this Airbnb in a great location! You are next to a bus stop and the metro is only a few minutes away by foot. If you are coming to this flat from the airport or going to the airport, it is only a 40-50 minute train ride without any connections, which is nice if you have suitcases and have never been to Paris before. Food is nearby, and so are grocery stores in case you want to take advantage of the kitchen.
The flat itself was spectacular, you can fit 2 people VERY comfortably, and 3 if two people do not mind sharing a bed. 4 people might be a challenge, but it is doable. The apartment feels modern and you have great views of the Eiffel Tower and the Pantheon. The views were to die for!!! You are in Paris, and it is nice to enjoy looking at it when you are back at the flat after a long day of sight-seeing.
The only downside to this apartment was that you have to climb just over 100 stairs on a staircase that is not easy to climb. Considering you will likely only go up and down the stairs 1 to 2 times a day, it is worth it. A large, nice bathtub is waiting for you in the apartment if you need to soak in a hot bath from walking around Paris all day and climbing stairs. BUT if you are not fit to make this climb, I would not recommend this apartment. If you can get past the steps, you really can't get a better deal for the money you spend!
