Although using a rewards credit card is recommended for all purchases, it’s especially beneficial when booking travel. Not only will you get plenty of reward points when you book, but often you’ll receive bonus points for booking certain flights, hotels, or car rentals.
If you want to book a rental through Airbnb, consider booking a month-long stay. Most European Airbnb rentals give sizeable discounts for stays of one month or more. Don’t be surprised to see discounts of up to 60-70% if you can handle living in the same place for an entire month.
