The ramp to enter St. Giles Wembly is as shown in the photo below. The ramp appeared to be steep and there is only handrail at one side of the ramp.
The accessible toilet at St. Giles Wembly was located at the lobby and could be found easily. It was big and bright and quite expensively docorated. The only thing I didn't like was the location of the basin. (See photos below.) It is not good for people who use side-transfer.
The accessible toilet of Cititel Express was quite a distance from the lobby and hidden behind a wooden door. A friendly receptionist led me all the way to the toilet. We had to go up a ramp and then past a long corridor before we could reach it. Then we found that the toilet was locked and she could not locate the person who had the key. I ended up using the one at St. Giles Wembly.
Conclusion: All new buildings in Penang are beginning to have facilities for wheelchair users. This is a good trend. But the designs of these facilities still have room for further improvements.
