Hi Kat,
I've been staying here at HK ParkView for about a month now. There don't appear to be any of these cables that you speak of very close by. As far as I can tell, that is hardly an issue.
Concerning the mist, YES. The entire small valley that ParkView is built in was covered/misty more days than not in the past 4 weeks. On days when I could not see past the neighboring towers from ParkView I thought it was cloudy all over, but a drive down towards Central or Wan Chai made me realize that only Parkview was sitting under the clouds.
I must admit we have also been looking for a place here and looked at more than 3 apartments here in ParkView (we are staying in the Suites until next week). It was very tempting, but the conditions of the apartments and the location made us decide otherwise. For the same budget, we found a much nicer place.
Hope this helps.
