Mills House Wyndham
We lived dangerously and used the Hotel Tonight phone app to book when we landed. The app offers lots of choices in Charleston. Decided on the Mills House Wyndham, and it was really nice, especially at a rate of under $200 including taxes & fees. Definitely stay in the historic area. Getting around from Charleston to Fort Sumter and other attractions is easy via car. And there are also organized tours. It's such a walkable city that you can spend a couple of days there without ever getting into a car. Enjoyed drinks and views at the Vendue Inn's rooftop bar and a superb dinner at Fig.
