Just a suggestion: clean the part of the bathroom where the water hole near the toilet is located, as it's brown and full of hair. Also clean the inside edge of the refrigerator door, as it's black.
I've stayed at this hotel several times, trying several room types. I like the fan rooms the most, as they're the cheapest and often out of stock. The low price, the standard hotel amenities, the 24-hour reservations, and the friendly and helpful staff are what make me happy.
