I really liked that this Airbnb is so conveniently located. Beside being located in the 2e arrondissement, it is literally right outside a metro station, Monoprix supermarket, and the Notre Dame is within 20min walking distance! I shared a room with 3 other people and even made friends and walked around Paris with one of them :)
The host washes and changes the bed sheets after every guest and maintains general cleanliness of the area. However, it still feels slightly dusty especially under the window or around corners (a result of double decker beds perhaps?) There is only one shower available so be prepared for long waiting times in the morning or at night.
The host is very friendly, sincere and helpful, though it definitely helps if you can speak Chinese. His French and English is not very good, so if you're lucky, maybe one of the other guests can translate for you.
All in all, 5/5 stars for the cheap accommodation in central Paris and no fuss experience!
