Yes, we could do the Ibis but I was hoping for something with a bit more character. I guess for one night it doesn't really matter. I'm looking for somewhere not too far to walk to/from the station with luggage. I will do AirBnB for one night if it is actually B&B, i.e. a room in someone's house. Still trying to sort out the itinerary.Veronica
I have no idea what you consider a reasonable price, but there are several Ibis hotels i Nice including one near the Port. For an overnight, we like thus chain. I don't know why you want to stay by Carrre d'Or but Nice has excellent transport and everything is pretty much walking distance.
Personally, I wouldn't use Airbnb for 1 night.
Good luck. I love Nice.
