Yes, the elves are very nice! They are a bit silly though, and not nearly as serious as the elves are in 'The Lord of the Rings.'
The elves were not nice. They were isolationists who mistrusted everyone else. Mirkwood was full of enemies. Look how they treated the dwarves, not nice at all, me precious.
Elves in The Hobbit come across is silly around Elrond's home. And the ones in Mirkwood were rather mean and captured the dwarves and held them prisoner. But in the end, the elves are fierce warriors and are instrumental in helping destroy the goblins and wargs.
In the Hobbit there is no attempt to ratify the existence of elves with the known rationale of the world. therefore they are fantasy.
Stay on the path, be nice to Elves, and make sure you have a wizard and hobbit. You will be walking or riding ponies for most of the way...... and remember to bring something you can use to fight off giant spiders!
They are talented craftsmen
There are lots of creatures in The Hobbit. There are hobbits, elves, dwarves, and wizards to begin with...
In the Hobbit, King Thranduil of Mirkwood, the Wood Elves' king, liked his wine from Dorwinion. His wine was also imported by the Elves of Mirkwood in barrels down the Forest River from Long lake.
Spiders, trolls and wood-elves
In The Hobbit, they are simply identified as "Wood Elves". Later, they were further identified as being Silvan Elves led by the Sindar, Thranduil (who is the father of Legolas).
The elven king in The Hobbit is the leader of the race of Elves that lived in Mirkwood.

If you are referring to the book "The Hobbit," we aren't told exactly. We do know that elves and dwarves had a long-standing grudge against each other. But it does seem as if the elves were trying to trap them, or at least to create an excuse for taking them prisoner. The elves in "The Hobbit" were more like the elves in Celtic folklore - silly, tricky, deceitful little fairies - than the regal, mysterious elves in "The Lord of the Rings." Legolas was a Mirkwood elf, one of the people that the dwarves encountered in "The Hobbit," and was not considered the equal of the Lorien elves.
The name of the valley is Rivendell, or in Elvish, Imladris.
The elves in "The Hobbit" did not know how the dwarves could have travelled there. They thought the barrels were all empty.
