Nice Lodging Ideas

A B&B would be my preference - because you get breakfast! You can find ratings on 25 B&B's in Nice on tripadvisor.com

You can check apartments, see if they'll let you stay for less than a week. Depends on where you're going. When our son was little, we still stayed in B&B's and just set up a cot or a nest of blankets for him to sleep on. With 4 adults, though, a 2 br apartment may cost less than 2 rooms in a B&B.

I've seen several posters reference www.vrbo.com as a site for renting apartments. Depending on the time of your for your trip, you might be able to find something for less than a week. It might be less expensive than two rooms at a B&B. Have fun on your trip!
