First, they always demand a tax foreigers should be exempt from, and if you book through Expedia they add it to the cost of the room. I've seen them increase the rate from a confirmed internet price before allowing folks to check in.
My first stay here was great, so I gave them a commensurate review. Since then I've had problems getting a hot shower EVERY stay since (at least 3 other times). They have to "switch tanks" sometimes, but the staff who knows how to do this isn't always readily available. Even when there is hot water, you have to let the tap run for at least 5 minutes before it actually gets hot, wasting water.
Their cafe on the 4th floor is open to the central stairwell, so every sound echoes throughout the hotel from about 5am, as does the sound of every guest checking in, open and closing doors, and the business on the first floor.
Finally, only in my first room was I able to diminish the light flooding into the room to sleep. Every other time, I could literally read by the light flooding into the room all night because there are no curtains.
