No 24h reception, but the owners are easy to contact and arrange check-in, even at midnight. Overall good condition of the room, however the building is clearly old. Paints half removed and creaking floors, thin walls letting many sounds go through. It's fine for one night, but I would not stay longer. My friends stayed 3 nights and did not complain: depends on your level of acceptation.
Bring your own towel, the one provided is clearly too small.
Very good location though, breakfast store just next door, 7-11 and small restaurants at the corner, local market next street and subway (MRT) station very close.
