We spent 20 days on Lanta, we moved from the north side towards the south, we planned on going all the way to the tip, untill we found Otto's.
We were first booked in for 3 days...after a day we then pushed it to 5, after 3 days we finally agreed to 7 nights here. THe room is simple, as one might expect with a beach hut style room. The bed was firm yet soft, not a springy box like some other places we stayed, the room was insect free, and they offered to clean it whenever we wanted.
The hut is located behind the restruant and bar, but it was surprisingly quiet, only Saturday night did the music drown out the waves. The beach here is great for swimming, and Otto's has free beach chairs and umbrella's, which they allowed us to bring drinks from the corner store down to (though we periodically ordered some snacks or beers from the bar, just so they wouldn't crack down on us...though I doubt they would have).
The vibe down at this beach was very relaxed, furthermore the small road is close to the beach, and there are plenty of conviences near by.
We also booked a tour through Otto's and rented a scooter for a reasonable price for the week.
Even though it does lack the true beach hut look and feel that the places on Long beach offer, it was our favorite place on Lanta.
