I have been working in Indoensia for the last 5 years and I love it. Originally from Hawaii, although I have moved around and traveled quite a bit : USA, Mexico, Colombia, Philippines, Hong Kong and most recently Brazil, Paris, & London :)
There was a key and keycard left at the front desk (which is open 24 hours) and staff who are able to escort my guests to my apartment when they check in (as they have done for quite a few other people without issue). Yes I like to personally meet all my guests when they arrive or at least before they go, but sometimes Im not available due to work or traveling.
For other guests: my place is 5 min from the airport. So if you head to the beach nearby, you will be able to see planes coming in from the ocean side. This beach stretches all the way down this side of the island (check it out if you land in the daytime). You can effectively walk the beach through the entirety of Kuta into Seminyak and on. Various parts of this stretch will look different from the others. Grey sand, white sand and even black sand down in canggu. You will see empty, to populated, to fishing, to super crowded areas with sun chairs and hawkers. You can see calm waters for those who cant swim, to surfing practice size wave areas, to serious currents. There is a big variety to choose from. Ive taken some of my previous guests to some of my favorite beaches and am happy to give advice based on what you are looking for.
