Booked via Internet and got a confirmation, upon arrival they didn't know about my reservation. Was not a problem, as there was plenty of vacancy, might be a problem in high season, though.
Stayed for a week in zone 3 for THB 550.- per night. Got a big room on the 4th floor, after I denied the one initially offered on ground floor, whch looked like a cell in jail.
Room was equipped with everything you need, bathroom is thai style ( no tub, no curtain = wet toilet paper, if you forget to safe it ).
Bars, massage, 7/11, restaurants, all in walking distance, one can easily walk to 2nd road. Baht bus passes the hotel as well, for coming back sometimes you need to change bus twice. No stupid questions asked or extra charge if you bring a girl or two.
WIFI in the room too slow, ok if you sit in the lobby. Hotel for this money absolutely o, has even a little pool..
