Mediocre 5-Star hotel in a bad location of Bangkok...

Mediocre 5-Star hotel in a bad location of Bangkok, for tourists that is. You are locked on that side of the river and pretty screwed without transportation and even then you are screwed at Taksin bridge, which you have to cross to reach town. There is a boat service to the BTS but only in the day.
What I like about the hotel are is the views, that are different from most other hotels in town and quite nice when you get high enough. Also the rooftop bar is not well know and therefore still a nice pace to chill - opposing to other popular rooftops with a view like Vertigo, Lebua that are way overcrowded.
Since end of 2016 a huge construction site is next to the hotel. This will go on for 1-2 years. You will hardly enjoy your stay, even if they give you a room facing the other side. The pool area should have heavy construction noise.But maybe that leads to some bargain prices over the two years.
Hilton membership guests will come anyway to spend their points.
