Spent two out of our 4 nights in Koh Lanta in this hotel. My better half couldn't live with the noise coming from the main road, which wouldn't be an issue for budget travel or if you have a tight sleep.
All in all - this place seems fresh, stands for sustainability and has great everything except for being on the main road. Helpfull with bookings of trips etc.
To have windows away from street is a luxury - i figured it's only 3 rooms in whole hotel that has it, be aware of ones without windows. Similar situation is for many hotels around main road - they might seem resort-like, but unless you take a luxury bungalow on the beach for tripple the price, you will have windows towards the main road. In that case - why not pick this, where everything else is just great.
Lady at reception is amazing, you get metal bottles with unlimited drinking water supply, rooms are clean, beds firm, showers quiet and great so as airCon. And the breakfast... one of the best in Thai. you get to pick each item of your breakfast (egg, bacon, type of bread, everything you like) plus a really good coffee.
Big thumbs up!!!!
