We went to the Clifton after cancelling our stay at the Banque Hotel down the street. (The Banque is the dirtiest, shabbiest hotel I have ever seen!)
Had a good time at the Clifton; creaky, narrow and clean halls, good views and a good restaurant with a slow but helpful staff. Good counter help and a generally good atmosphere. (The town of Folkestone is no destination in itself although they seem to be trying to improve things...)
