Overall, I like this apartment hotel.
Pros - Location is great, is on a block next to main streets where you can find restaurants, supermarkets, stores. Is 15 minutes walk to Louvre Museum and close to their train stations. Size of the apartment is fine for 4 (2 Adults and 2 Teenagers) with 1 bedroom, 1 sofa bed in the small living room with the open small kitchen, small toilet room, and separate shower room. The Wi-Fi works fine and the apartment seems clean.
Cons - The negatives are based on my personal experience in this apartment hotel. We got the apartment on the 4th floor; their stairway is small and curves with uneven size steps. They do have an elevator but is small and only fits a maximum of 2 people (plus size, 1 person), if you have big luggage, it might be an issue. For the apartment, we had issue with the door keypad as the battery was running low and didn't work a few times. All communications with the staff or IA are through WhatsApp and a bit hard to find a real person to communicate our concerns. They did replace the battery the next morning. They have a wash/dryer combo machine, but we can't figure out how to operate this thing correctly or it just works differently than USA machines. Just to dry my clothes seems to take 5-6 hours and it bangs loud. It also got so hot, it ruined my pant and burned off the glue on the zipper. AC doesn't run cold enough, I think is EU thing. Thank God the weather was nice when we were in Europe at end of August.
