My first impression of the hotel was not good (my first visit was more than a year ago, but this writing was based on my recent visit on Sept 30, 2013). The very steep ramp at the entrance gave me that first impression. But if you phone the hotel and tell them you are coming in a wheelchair, they will reserve a special car park right in front for you. They will also assist you to go up this steep ramp. So the service wasn't bad.
The passage way to the garden (see the arrows in the photo above) was originally the five foot way (kaki-lima) of the terrace houses that have become part the hotel. In the old days, "kaki-lima" were build in front of every terrace house to provide shelter from the tropical heat and the occasional tropical downpours.
The photo above is what you will see when you turn into the garden. You shouldn't stop there. You should go to the end of this pathway and turn right into the deeper end of the garden. The place is beautiful, shady even under mid-day sun.
If you enter the lobby of the hotel, you will see the counter shown in the above photo. Turn right if you want to go to their restaurant or the accessible toilet (located behind the lift). Yes, this small hotel has a lift!
The illustrations below explain the "side transfer" method and why wider space (not less than 600 mm) is needed beside the toilet bowl. For more details please got to my post about accessible toilet. The link is HERE.
