"I do not like this chair."
Translation:Мне не нравится этот стул.
yes it's in accusative form (inanimate masculine noun uses nominative https://www.duolingo.com/skill/ru/Accusative-Case%3A-the-direct-object/tips-and-notes).
нравится/нравятся = "like"
люблю = "to love [a person or pet]" or "to like [a thing or place or activity]" EXCEPT (according to olimo) "You can't use любить for something you try for the first time." A gift would be something you "try" for the first time, so you have to use нравится. "I like to eat borscht" could use люблю.
But exception to the exception: Duo accepted Я не люблю этот стол, but might not accept я люблю этот стол - According to the Tips and Notes for the "Inf & Like" module https://www.duolingo.com/skill/ru/Infinitive%2C-Likes-and-Dislikes/tips-and-notes любить is preferred for negation of liking, as least for activities, and apparently for things.
Мне is the Dative case form of Я.
With нравится/нравятся = "like", the person doing the liking is put in Dative case, which usually means, in the example of Мне, "to me". You may understand this better if you think of нравится/нравятся as "is pleasing", so the Мне нравится парк = "The park is pleasing to me", translated idiomatically to "I like the park."
Note that the thing which please "me" is in Nominative case, which means that it is actually the subject of the sentence. Мне is an indirect object.ц
