OK! OK! I can answer the part of the question on how high an apartment a monkey can climb! I have a unit on Miami Green opposite Ferringhi beach on the 14th floor! I chased one off my kitchen window one morning. She was there with her baby clutching her belly! That was 14 floors.....don't ask me how she did it! I use the apartment once a year, hence it is vacant most of the time. I suppose she figured out that window sill was a "safe hang-out"? There is a landing just below the sill where, judging by the amount of poop, birds hang out also!
On transport, I found the rapid Penang buses reliable and comfortable.
Certainly no "dog packs" roaming around. Malaysia is a predominantly Muslim country. As such dogs are usually "not looked on favorably" by Muslims and hence, as long as I can remember growing up in KL, their proliferation as "gangs" is very controlled. They just shoot them after they have been caught. Maybe, since 30 years ago, they have more humane methods now? In any case, you will find this to be the case throughout Peninsular Malaysia. Any "bands of dogs" (even a loose dog seen too often) will be called in by the Malays!
On drying clothes: having lived in S'pore, there is strict control on cloths drying there depending on whether you live in government provided housing (HDB) or private. In the HDB units, you can do the drying off long poles in the back (usually off kitchen exterior walls - provision is made with pipes in walls to stick the rods in!). In private condos, they are forbidden totally (again dependent on management) - front or back altho' people have hung them inside balconies. In Penang, I think the standard by-laws of HOAs forbid the drying off balconies and such but again, enforcement dependent. Dryers are not common in apartment in Penang, as far as I know altho' you could purchase one!
Hope this helps!
