Let me help to elaborate since I owned a property at OUG Parklane, and I passed by the area daily.
1. Too close to PPR, lot of B40 problem. Saying so, the whole area is jammed with car parked on the roadside.
2. The area in front of the PPR and LRT always flood when it rain heavily
3. Near industrial area, so u can expect a lot of lorry. trailer using the same road everyday. The road will not be as nice as u thought it will be.
4. Again, too close to PPR. U will have a lot of problem later, trust me. We have enough problem dealing with these PPR folks from our OUG Parklane condo. Rempit, drunk people, gangsterism, u name it, they have it. U can google news about dead bodies found nearby. In last year, i think 3-4 bodies we found in the river, near the river, at dumping area, etc.

There is also abandoned construction nearby, but recently they revived the project. Another condo, just next to sunway. U can imagine the jam with all these condos, the infra is still the same. The road at the LRT is 2 lane, but because PPR folks parked on the roadside, only 1 lane is accessible. It is a massive headache to get  through it everyday.

Edit: I forgot another Condo ongoing, Exsim Condo. So around the area, u will have Exsim, sunway, como, OUG Parklane (its high density condo), PPR, Platinum OUG, Bukit OUG condo and townhouse. Bear in mind these are all condos, and the infra has not been upgraded in god knows how many years.
