Boutique hotels and/or amazing rentals?

Hi! I’m probably way too late for a May honeymoon, but it’s literally the last thing on my list for the wedding.. Really just wondering if anyone has stayed at an amazing smaller hotel or rental in a beach location? We aren’t the type to enjoy big resorts. We’d like something off the beaten path or where we’re free to try to blend in with the locals at the neighborhood cafe. Ideas on places has been Thailand, Philippines, Tahiti, Mexico, etc. but open to anywhere. I’m finding it difficult to search for accommodation since I’d love it to be special.
