"Cette maison est bien."
Am I correct in thinking that, in this case, "bien" is describing the house and is therefore an adjective?
If this is true, then "bien" can be an adjective as well as an adverb.
Please could you tell how to know when to use "bien" or "bon" as an adjective.
In other words, why did the question not read "Cette maison est bonne" ?
