Visiting Kota Kinabalu.

Me and my friend has bought a flight tickets to KK, Sabah but has not plan anything for now lol. We will be there for 3 days (28-30th) before going to Sarawak. Would like to know a great place to stay (preferably near to the airport) and friends has suggested to stay around Sutera Harbour? Is that a good choice? We love beach side and budget is around RM400-500 for two nights.

Oh, would love to see any activities suggestion! We love food, chilling, beautiful scenery for instagram post hehe, museums, art gallery, meeting people and making new friends.

Also, is it cheaper to travel by grab or rent a car?

Thanks in advance Sabahans!
