To be honest, nothing which really comes to mind...
My friends and I stayed at the villa Tioman, amazing villa with perfect set-up - common area over looking the luxurious garden and pool. The display of the villas is done in such a way that you really have the feeling to be alone - I quite like the size of the resort with only 5 villas, it really gives you the feeling of exclusivity. Most importantly, the best thing we encountered was the friendliness and attentiveness of the management and staff! Whatever request we might have, we never heard the words "not possible". The staff was very discreet and extremely nice. The check-in was brillant, we arrived in the evening and got greeted by the owner directly at our villa with all necessary info needed to make our stay the most convenient. Very good restaurant recommendations by the way! They even provide a mobile phone, pre-paid with all the needed numbers on speed-dial.
In terms of location, you are 5min walking distance from a strip full of restaurants, coffee shops and 10min distance from the beach. By taxi, you can reach easily within 15min the various beach clubs on Seminyak (KuDeTa, Potato Head...).
All in all, great holidays in a beautiful surrounding and the kindness/attentiveness of the staff to help out just made the holidays ideal!
