Tung's place is immaculate; extremely clean, nicely stocked, and very thorough, accurate, easy to follow instructions and guides.
I found the stay to be a blend of staying with your loving relative who goes a step beyond what's necessary to make sure you are comfortable and feel at home, and a nice hotel.
He had chilled water and sparking soda ready when I arrived (all I drink is water and sparking soda, so this hit my sweet spot!) and I was starving from the travel and didn't stop to get food and he had a nice variety of snacks on the ready as an amenity.
I also found Tung to be extremely nice and user friendly (great customer service). He was very responsive to all of my inquiries, and went out of his way to accommodate my early arrival.
I wasn't thinking in my rush to get on the road, but I should have left a tip (sorry Tung!).
