If you want to monitor Airbnb for the best deals and be notified when they come up, Alertbnb is a great option. It lets you set up customizable alerts for price and availability of listings anywhere in the world. With features like instant booking, saving listings for later, and filtering alerts, it's geared to automate the process of finding the newest and cheapest listings. You can sign up for a free account or upgrade to a paid plan for more advanced features, so it's great for travelers who want to keep an eye on the constantly shifting Airbnb landscape.
Another service worth checking out is AiRial, an AI-powered travel planning service that helps you generate entire trips based on your preferences. While it's geared more toward generating personalized trip plans than just monitoring Airbnb deals, it can help streamline your travel planning and lead you to affordable and suitable accommodations through its trip generation features.
If you prefer a more community-based approach, take a look at Mindtrip. The service offers recommendations for destinations, hotels, flights and restaurants, and lets you create and share customizable itineraries. By seeing and contributing to others' plans, you could be inspired by different travel styles and find off-the-beaten-path deals on accommodations. It also handles booking and reviews, so it's a good all-purpose travel planning tool.
