We stayed at the apartment for a month in 2022. Here's the breakdown of my three star rating and I hope it helps you understand more about the wonderful things about the apartment and the things that need improvement - plus some general tips of the area.
Cleanliness The apartment was really dirty when we arrived. It has been turned-over, so fresh sheets and general tidiness, but the apartment had not been deep cleaned in some time. We found mold in the bathroom along with dirt buildup on the walls and baseboard, the carpet was matted with hair, dirt, and gum. The floors were greasy feeling, the sheets had been washed but there was hair stuck to them... you get the idea. The place really needed a good, deep cleaning. I was traveling with a baby so I needed to clean the floor immediately and ended up doing the deep clean myself. I contacted the host and she offered to have a cleaning person come but did not refund my cleaning fee.
Long term stay viability - The apartment can be booked for long term stays but I found that the apartment lacked things that made that a comfortable experience. The kitchen counter space is very limited (mostly taken up by appliances) and the kitchen utensils are sparse. For example, there is one, small, wooden cutting board. It has seen some serious wear as well. The pots and pans are cheap Teflan and very scratched up. The fridge is very small. Beyond the kitchen, the living space can accommodate a remote work setup but really if there is only one person working or if you don't mind taking up the entire living/dining room with your work gear. The living/ dining room area is much smaller in person than it looks in the pictures so keep that in mind.
Beds- The beds themselves were pretty comfortable if you like a more firm mattress. They are typical small doubles. The sheets are cheap so a bit scratchy but there were a few extras so we could launder them regularly to help with that. The pillows are old and lumpy so I definitely suggest bringing your own pillow if you struggle with neck issues. I went out and bought one during my stay after waking up with a stiff neck. The mattresses are very very dirty so make sure if you have kids that you are keeping sheets on the bed at all times. I would suggest that they be replaced.
Noise - The apartment is a corner apartment that sits between a side street and a main road. The side street is fairly quiet except for the moped riders that store their bikes there. Amplifiers are popular with that group so heads up. The main road can be pretty loud especially on weekends so I do not suggest this apartment for light sleepers.
Location - This neighborhood in Paris feels like a working class neighborhood and is nothing fancy. If you want more cute shops and restaurants, I suggest staying in the 5th or closer to Bastille. However, we did discover that if you walk up to Charrone Street, you find yourself in a lovely little pockets. And the metro has several stops for almost all lines with 2-6 blocks of the apartment. We took the Metro everywhere and were very pleased with how convenient that was.
Bakery - We were on a mission to find the best croissant in Paris! Luckily, our mission concluded that the best one we could find was just around the corner from the apartment. We went every morning (except Sunday when they were closed) to get fresh croissants. Tips - Wed thru Friday mornings are the best. The bakery is called Maison Doucet - Boulangerie-Pâtisserie.
