SM Hotel is a nice enough budget hotel. For the price I paid it was good enough, and the location (about 5 minutes by Tuk Tuk to Patong Beach, 10 minutes to Karon Beach) was perfect.
Positives: The staff were exceptionally kind, and tried to help my wife and I out as much as they could. The pool was nice; however, like most of the hotel the pool area was cluttered and could have been nicer. The rooms were ok, again for a budget hotel.
Negatives: If the hotel cleaned better and picked up the clutter everywhere this would be a very nice hotel. The pool area and the roof deck are very dirty (the roof deck is unusable in my opinion). The rooms were dusty when I arrived, but I complained and the staff dusted for us quickly.
Again, for the price it's worth it but with just a little bit of effort it could be so much nicer.
