The apartment is right in the middle of the busy shopping street, that does mean street noise, but you're also within easy walking distance of the train station and everything in Nice. And with the doors closed, the noise from outside is significantly reduced. The apartment itself is basic, but complete, the kitchen is well equipped and I really liked the balcony. Also, the personal page you'll get access too after booking is complete with lots of information.
The sleeping sofa wasn't too comfortable, at least, that was what I thought and I found it rather unique that for a short term holiday stay, you only get one roll of toilet paper and you'll need to buy yourself more toilet paper if you're out. In years of staying at many different apartments, this was a first.
