I just moved into mk bayu end of 2017.
- tbh the older apartments do lack that wow factor, but i think in time with refurbishments it would fine.
- a bit of renovation in your own unit will make it so much better than the newer apartments, cause u can get alot more space for ur budget, unless u have an unlimited budget then just go for the new ones.
- the older condos seem to be built with more land, and i guess the developers were more generous in making the spaces not feel so cramped.
- but facilities wise, needs alot of improvement, but if u dont use the gym then probably u wont really mind.
- as for living in MK, its a good neighbourhood.. police security is tight, u can walk to the nearby malls from ur condo which is quite nice, and if you normally work or hangout at the areas surrounding MK then its also a plus.
- traffic situation is good, i leave the house at 8am, and its quite clear, takes me 10mins to exit the MK area on average.
this just my 2 cents

goodluck to all the buyers and sellers!
Older part of MK is a GEM... You wont get that anymore in Klang Valley
The future hot spot will be at KL Metropolis, Kompleks Kerajaan and Duta North area.
