With most new world tarantulas, you have to worry about urticating (irritating) hairs more than you have to worry about their bite.

Also, only the females make good pets. The males live for one thing- breeding. They reach maturity, go looking for a mate, breed, and die.
As the females rarely stray more than a few feet from their burrows, and you found it in your living room, I'd wager it's a male, and was looking for some loving.
