Angela was a very good host. It was my first time using Airbnb, and she was very good in terms of explaining how things worked, and promptly replying to messages (always replying within the hour).
The Flat is in a very good location on the 5th floor of a building with a lift. There is a carrefour across the street, and many other shops a few minutes away; it's about a 7 minute walk from the train station, 2 minute walk from BD Victor Hugo, and within 10-15 minutes you can walk to most areas of Nice Centre Ville.
This is my first time using Airbnb, so I can't really compare to other places, but the flat was simple and comfortable. Everything worked well, and the flat was clean on arrival. The flat stayed relatively cool (I stayed for 3 weeks in June) despite not having air-conditioning, and it was well lit.
Im a very heavy sleeper, so this was not an issue for me, but noise may be an issue for some in the bedroom; you can hear a bit of noise from the street, and also the neighbors' television on some nights. But overall it was a good experience, and I would recommend the property if you're not a light sleeper.
