That was our first holiday in Thailand, we spent two nights in AoNang then we moved to Koh Kwang sea view and as we are not party animals we felt very happy there, the view from the balcony -unbelievable, just 10 metres from the beach,when we came into the room - we were amazed. The room was very spacious, very clean, they cleaned the room everyday properly.
Yes, the only minus was that the Aonang town was 20 minutes drive by tuk tuk or taxi, 550 Baht one way if you bargained hard, that could affect your budget BUT directly in the hotel you can hire motorbike. The owners were very nicem very helpfull, we felt almost like at home, they helped us with organizing the trips. The breakfast was OK, but I personally missed a challenge, coffee, toast, jam and three eggs every morning. I hope I will come back one day, Thailand is amazing country.
