One of the default apartments KoHubbers tend to end up due to it's affordability and proximity to KoHub. The apartments are nothing fancy but clean and have some amenities like microwave, television etc. A negative is due to its location directly on the main road it can be a bit noisy with scooters and pickup trucks whizzing by. Though if you get one of the rooms a bit further in this becomes much less a problem. They also have some cheaper windowless rooms, perfect for night owls that don't want to be woken by the pesky sun. I choose one of the "deluxe" rooms that lies by the large upper patio (that anyone can use, so don't choose that one if that would bother you). Despite it's the larger size it was oddly devoid of any furniture to occupy it ... maybe that's been fixed :)
Monthly rent is around 15 000 for peak season (12 000 for a smaller windowless room). For green-season, this can probably be bargained down to 10 000, but with so many more alternatives available then it might not make as much sense.
With Pra-Ae apartments as most accommodation in Lanta you get best deals and up-to-date availability in person, but they actually provide pretty good prices booking online, through booking.com for instance, if you book it a few months in advance.
