1. upon loading, the web site immediately asks permissions for sending notifications and access to my location - that's too early and because of that, of course, "No, thanks". Notifications about what? Location - why? Since it's not mobile app and I didn't read the description before installing it, the request should be done only after some explanation of service is provided.
2. False data (and this ruins the whole idea). The trip from Moscow to Iceland is unlikely to cost $500 for two nights/two adults and when your service shows 5500 Rub per night average price for stay, it does not offer any accommodation less than 80KRub per night. Finding the flights at declared price is impossible: there's no UI to specify dates, as requested by error message (and minimal prices cannot be found by search on specific dates anyway).
All that said, it's too early to discuss the result - fix the bugs and UX issues first.
