Place was really nice and clean, despite the apartment being in a busy area, closing all the windows got rid of pretty much all the noise which was really good! If you're a light sleeper then this maybe a little difficult but for us overall it was perfectly fine. Communication with the host was really quick and we weren't left waiting for a response for hours on end. Connections to transport were ideal as there's a metro pretty much outside of the apartment building, it's also around a 20 min walk from the apartment to the Louvre which shows how much of a central location you're in. Be mindful if you struggle with stairs as it can become tiring after walking around all day and coming back to the apartmen, overall though this was no major issue for us looking back, just a bit tiring in the moment! There's a Lidl around 5 mins away with loads of restaurants and cafes at your disposal as well. The area is supposed to be known as 'The Ghetto' of Paris, however we had no issues as there's always going to be areas like this wherever you go! Despite this, the area was really nice, we were happy to go out as a group of 3, probably wouldn't want to be on my own late at night but as said previously, you can say this about anywhere!
