First off, the rooms are really nice, can't really complain about the room. There is no wifi in the room and the wifi in the reception and restaurant is pretty awful.
The superior rooms are way better than the regular ones. The regular ones are on the other side of the road... so you have to cross the road to get to the restaurant, pool and beach. Pool is pretty small but ok. The fossets leaked water in 2 rooms.
You have to know that Khanom mostly receives Thai tourists. It's almost deserted in the week but is fully booked on the weekends. Thai tourists are pretty loud and they do some weird things with an "american breakfast", for example they put some nasty vinaigrette sauce all over your omellette. There are 2 big building sites near Talkoo, so there is some noise.
The staff is pretty bad at English and everything takes a really long time. If you go to Khanom arrange your own transport because there is zero public transport and Talkoo charges 50 baht per person for a 3km ride to the minibus station which is utterly ridicoulous. The food is very expensive and you have to walk pretty far to find some.

I was in the beach bungalow near the beach. Nice and clean, to the beach about 30m, between bungalow and beach swimming pool. Wifi didnt work at bungalow, nearer reception worked. Kilometres sandy beach. Mostly thai tourists, nice and peaceful. Motorbike/car can be parked outside of bungalow.

We booked a week in the "beach front" bungalow. I think there are only 2 or 3 of the beach front bungalows. They are not TRULY beach front, but you are closest to the beach. The bungalow was large and clean with a large bed, sitting area, and well-appointed bathroom. The wooden finishes in the bathroom we thought were a very nice touch!

Being that Khanom is a little further off the beaten path than most tourists go, the english is not very good. Don't hold this against the staff members. All staff members were very friendly and accommodating! In Bangkok you might be able to get on without the phrasebook, but dig it out of your backpack when you hang out in Khanom. Try your best and you will get kindness in return! A benefit of being off the beaten path is the fact that the beaches are absolutely deserted. We walked around on the beach for at least 3 hours and only saw 3 other people -- and they were locals. If you are interested in heading to town or checking out the sights, you'll probably want to rent a moto. Getting around here is pretty difficult without your own transport -- Khanom town is several km away. The hotel staff were happy to shuttle us back and forth a few times, but it would have been much easier (and probably cheaper) to rent a moto.

Food in the restaurant is a little expensive, but very good. I would advise opting out of the included breakfast when you reserve. It is "American" and, while filling, left me wishing for a local breakfast. I think the sausage was actually a hot dog. I ended up getting a little sick while in the area and the restaurant staff provided a more bland meal of toast and chicken soup when I was having trouble eating.

A tip for the bungalow dwellers: Our bungalow had a gap in the door. We didn't see any bugs in our bungalow the entire week, but just to be on the safe side, I stuffed the gap in the door with a towel so we didn't have any overnight "visitors."

Overall, would definitely stay here again if in the area. Will probably rent a moto next time, though!
