Disliked: Cleanliness

Good for overnight stay

The curtains were stained, there was hair on the shower wall, the refrigerator was not turned on, and there was a metal bar in the shower upon arrival. The bed was clean but the pillows did not provide adequate neck support. You have the old-fashion AC you manually turn on and adjust the temperature (located against the wall by the window). There's also lack of ventilation in the bathroom, no fan available. Not a bad place to stay for the night but would not plan for more than an overnight stay here. There's also a lot of construction in the area (August 2025).
