The location was great. The apartment is located about a minute from the nearest metro station. It is also a 10 - 15 minute walk from the Arc. There are lots of places to eat within a 10- 15 min walking distance from the apartment. The street the apartment is on has about 3-4 places alone. It doesn't get more central Paris than this. There is also a grocery store and pharmacy pretty close by as well.
The apartment itself was very clean and as seen in the photos. They even had cleaners come in and clean every day (kind of like a hotel). The listing says 3BR/3BA. It has 3 bedrooms. The primary bedroom has a toilet and a shower. The other 2 bedrooms each have showers as well. However, there is one toilet in the main hallway it's more like 3BR/3showers/2toilets. We were a group of 5 and on 2 occasions one of us had to have a cold shower. My guess is that the 4 of us took too long and the hot water ran out.
All in all, we had a great experience. The host let us check in early as we arrived earlier than check-in. They also let us check out late as well as we had a late train leaving the city. They were responsive to our requests and if I'm ever in Paris again I will definitely be staying here.
