Hey, very good idea and nice execution. I like that it finds my location, even without asking or requesting permission. Extra points for having a track prices option.

I have a couple of suggestions/recommendations if I may:

- Put a Bortle filter so that hotels on specific (dark) areas can be selected. I understand this is a bit difficult but it would make an even better filtering option.

- Localize it, give us an option to see prices in different/local currency. Currently it's only visible in USD.

- I can see the Affiliate ID from Booking, perhaps it would be better to mention this somewhere to avoid complaints from users.

- Perhaps add a popup/permission notification for accessing location (see previous point as well).

- Put an info/about page so that you can give more info and also take some credit for your work.
