I got here very early in the morning from the airport and the staff was available and even friendly. Throughout my stay they seemed genuinely kind though limited English(but sure better than my Thai). There was a mix up with my room and they booked it out from under me after a few days stay...(see limited language comment) I had a single/shared bathroom on the 4th floor, good fan, window opened to garden, not too noisy at all by big city standards. (some neighbor room noise but mostly whited out by fan) When I arrived the whole place was very clean, but it did not stay that way...maybe they clean once a week? The rooftop area is OK, nothing special, but probably a good spot to rest and wait out your room availability and/ or your jet lag. Breakfast was good and the coffe thick and tasty.
The hot water worked well, just need to get the buttons pushed right and it was good. They were out of towels??? And the floor mat in the bathroom was a bit funky after a few days.
It seems that most of the guests were European and a bit older than the usual hostel crowd. Lots of smoking and TV in the group areas. Probably a good place to connect with others, which is what I usually do, but there was not a lot of friendliness here...perhaps language differences, but that is usually not a big deal as I speak a smattering of a few.
When you go out, make sure to take a card with a map. Taxi and tuktuk drivers had a hard time finding it and the map was essential. On the mainroad you can take the 65 or 33 bus to the Grand Palace area, walk to Kho San, and nearby is the river landing to catch a water taxi.
I would probably stay here again but it would not be my first choice.
