The apartment is located well in the city that is close to the Parmentier station and also to multiple restaurants and shops. It was perfect for our Paris trip and for getting around the city. It is a tiny apartment so I would only recommend it for two people. It was suitable for us because we would only go back to sleep. I appreciated the fruit and bottle of water that was waiting for us when we arrived.
There is no AC and a small table fan which we had to turn on the whole time we were at home because it would get really hot. This was sufficient for us in June but I don't know how the heat is in the later summer months. Also the kitchen compromises of a mini-fridge and one electric countertop stove. It may be enough for simple cooking but it may be harder if you are making more complicated meals or using more than one pot/pan.
Some of the features that we really appreciated in this apartment: a safe (great to store your valuables/passport), a heated towel rack, and a free laundry machine (it is located right outside the apartment between your unit and the one across from you).
Note: the apartment may be a bit difficult to find but when you enter through the main doors to the complex, turn to your left to section A. Take the stairs to the first floor and then make a left and go to the door on your first right. There should be a box with the key and when you open that door, your unit will be the door on the left. The apartment was hard for us to find the first time so hopefully this will help you find the place!
