Hi @Shafeeqah0 I don't know which words would be best, but you may want to avoid using "4 star" on Airbnb. It's a great TGGSA rating for a hotel, but on Airbnb an average rating of 4 stars is low. Rather mention other aspects instead of the stars, as it may be confusing.
Most agree the using words like "Chic" and "Luxury" are not helpful in your title, as these mean different things to various guests. It is better to highlight what is unique and special about your amenities and location instead. You can read your guest reviews and pick up on what should be in your title. I saw things like:
Great views (Mountain, City, Waterfront)
Pool
Free Parking
Gym
Close to everything - (some walkable) mentioned Waterfront & Long Streets
