We loved staying at Pattara House. When we arrived, we were greeted by the family that runs it and they took the time to use our names whenever they chatted with us.
We got a whole bungalow to ourselves and it was massive. It had a nice little deck as well as a fridge and big huge windows. The bed was comfy, the AC worked great, and the water was hot :) We were so happy to be staying here!
It was close to everything you need -- food across the street, motorbike rentals, and the beach not too far of a walk away (15-20 mins), which is perfect to keep it nice and quiet. The internet was down for two nights while we were there but once it got back up and running, it worked fine. We had our laundry done as well and it was a good price and prompt. Oh -- and they cleaned our room daily! Even when we didn't leave the bungalow till later in the afternoon, we still came home to a nice made bed :) Definitely a treat!
Overall, staying at Pattara House really made our trip on Koh Samui memorable. We enjoyed sleeping in, relaxing, and coming back to a nice, big, clean private bungalow each night!
