The good: This apartment is VERY convenient to multiple metro lines and the apartment is very spacious. You can easily get to the apartment via RER B, to Versailles via RER C and all over Paris on the metro. The proximity to Chatelet also means you’re close to a Monoprix for groceries. The apartment is also located a few blocks from Rue Montorgueil which has some great places to eat and is always bustling. The living room/dining room area were very open and spacious and would not feel crowded with four or five people sitting around. The mattress was fine, the sheets were very clean, and the comforter and pillows were very nice. There was a bag of chips and a bottle of wine waiting for us when we arrived. There was a daybed in the living room that was not a great couch (the back cushion was too short for the gram) but would have been very comfortable to sleep on for 1 person. The apartment has 2 security doors before you get into the central courtyard and the stairs to the apartment (3 short flights to the apartment - not bad at all) and felt very safe and secure.
The warnings: The bed was ok but definitely a double bed and not a queen-sized bed, my husband ended up moving to the top bunk because there really wasn’t enough space for both of us, and the top bunk was just a thin ikea mattress. The kitchen was not very clean and some of the silverware in the drawer had bits of food stuck to it. The tiles in the bathroom were cracked, the towels were clean but smelled like they had been left too long in the washer before being taken out to dry, and the washing machine had a drying rack with no legs that we ended up having to prop up on the only 2 dining chairs to dry our clothes.
Additionally, as a warning for families with children- the couple of blocks surrounding where the apartment is located has a number of peep show joints and some adult video stores.
Overall, I would rent again because of how convenient it was to all the transportation and how spacious the living room/eating area was but one needs to have a decent tolerance for dinginess.
