We have stayed at this DoubleTree by Hilton before, including around the time it first opened, so unfortunately the difference today is quite noticeable.
The hotel seems to have gone downhill considerably over the years. The rooms and common areas do not appear to be maintained to the standard we would expect from a DoubleTree by Hilton. Our room also had a very strong and unpleasant smell, which made the stay much less comfortable.
The service was also disappointing. Communication in English was extremely difficult, and overall the level of service did not feel comparable to what we experienced when the hotel first opened.
For a hotel carrying the DoubleTree by Hilton name, we expected a much higher standard. At this point, it feels more comparable to an average local hotel, and in some aspects even below that level. Considering our previous positive experiences here, it was disappointing to see how much the property has changed. Unfortunately, in its current condition, we would probably not choose to stay here again.
