I can´t understand this sentence in Spanish very well.
Quédese, disfrute el ambiente, después yo mismo la llevaré a su casa.
Does it mean "Stay, enjoy the ambience, later I will take it to its home by myself"?
ambiente means also "environment" and "room"
yo mismo - I myself
The verbs indicate that the person is using the formal Usted form (Quédese, disfrute) so the "la" (direct object pronoun) refers to this Usted - a woman.
"Stay here and enjoy the environment/the room and I will (personally, myself) take you home later".
the pronouns can always be ambiguous without context or the clarifying prepositional phrases, but I think this just says... "I, myself, will take it to your house."
Stay, enjoy the moment/the environmental, later, I will carry you home.
