meilleur ou mieux

Question

"Cette maison est bien. Oui, elle est mieux que l'autre." Since this sentence is describing a noun which means we are using an adjective instead of an adverb, shouldn't we use "meillure" instead of "mieux"?

Bonjour Helen,
Alan described very well how you can have ‘être’ + mieux / meilleur.
Remember: bon → meilleur    bien  →  mieux

Ce gâteau est bon (meaning ‘délicieux’) = this cake is good
     mais ton gâteau est meilleur = but your cake is better
Cette maison est bien (meaning ‘de bonne qualité’) = this house is good
     oui, elle est mieux que l’autre = yes it is better than the other one

I hope this is helpful.
Bonne journée!

When the verb is être, you can use either mieux or meilleur, so the choice depends on the following guidelines in the lesson:When to use bon/bonne (adjective) and therefore meilleur1. qualifying something as good/better/the best for a usage, or good/better/the best in taste (food)2. qualifying someone as a good/better/the best person or good/better/the best at somethingWhen to use bien (adverb) and therefore mieux1. making a general statement with être about something or someone being fine/OK/better/the bestThese guidelines are not very clear, and I expect sometimes mieux and meilleur will both be possible.
