I had the pleasure of staying here with my wife for 5 days in August. We were impressed by the neatly designed rooms and the cute decorative use of bamboo. The rooms were comfortable and air conditioned, and the staff were mostly very helpful.
The hotel's bar/restaurant offers some excellent food and cocktails, although keep in mind that it is a bit more expensive than smaller nearby restaurants. The pool is nice and, although small, it was always available and clean while we were there.
The location of the hotel is very good. It is right in the center of Karon, with plenty of restaurants, bars, markets, street food, massage parlors, and salons very close by. There are no real pavements to speak of, but you will get used to that. Just keep a close eye on the traffic! I also highly recommend insect repellant, as the open drains attract mosquitoes, as is the case in many towns in Thailand.
The beach, which is quite beautiful, is also just a short walk away. The umbrella seats are great value, and you can enjoy fruit drinks from nearby vendors. Pay close attention to the flags though, as the rip current can be dangerous.
Like any cheaper hotel, the Bamboo House certainly has its idiosyncrasies. For instance, the bathroom doors do not extend either to the floor or the ceiling, which may create an unexpected challenge for new couples. In addition, the outdoor breakfasts tend to attract rather a lot of bees, which can be a little unnerving.
But all in all, I'm extremely happy to have stayed here. For the traveler who is on a budget but appreciates the comfort of a nice hotel, I highly recommend this place.
