I would say that staff service and cleanliness have some room to improve.
when I checked in, their staff told me there was no available room even though the reservation was completed a few months earlier. A moment later, my reservation was given a free upgrade to a better available room (VILA sweet). I appreciated this unexpected upgrade, but I felt their management was not so organized then.
The VILA sweet was spacious, and equipped with a small swimming pool on the balcony.
but, we found 4-5 almost-dead cockroaches in a drawer in the kitchen. The hotel manager came and apologized, but this was surely a terrible memory of the trip. (compensated with a free airport taxi in the end)
Besides, due to the location of VILLA on the 5th floor, a lot of trash keeps (paper, swimwear, shoes, etc) dropping on the balcony from the upper floors. Sometimes staff came to our room to pick them up. We never knew what to fall next, we could not stay outside without the parasol.
As a good point, I liked the location, easily accessible to shopping malls and restaurants around Tumon Bay. It was convenient to go shopping even within a 5-minute walk.
