The apartment is small but functional and includes all needed amenities.
The pros:
The apartment looks exactly as in the pictures. It is not too small and was absolutely sufficient for two of us.
The kitchen is well stocked with pots, pans, plates, utensils. The place was recently renovated and still has the feeling of new. The shower is good, and the heated towel rack keeps the towels dry and warm, which is great. The location is great: close to Metro lines 4,5,7 and RER B (to CDG airport), it was easy to get from and then back to the airport. There are supermarkets just steps away.
The cons:
The bathroom door doesn't lock. It was not a problem for us as only two of us were there. The mattress of the sofa bed in the living room is not great, it would be good to add a pad to make it easier on your body during sleep. There are no window covers, though it didn't disrupt our sleeping as we traveled in the winter.
Overall, we recommend the place and would stay there again.
