Mimpi,
Nice looking "Rental House".
Suggestions? I will give you the same lecture I give the Balinese. Bali has developed more than enough accommodation and restaurants, but tourists want to do other things, as well as eat and sleep. Eat and sleep are already covered.
A Canadian friend had a good idea for an Ubud business. She opened a shop that teaches tourists how to make silver jewelry. The students get to keep what they make. Her shop was making money in the opening first week. She hired a master silversmith from Celuk to run the classes, so the students learned from the best.
Ask yourself what Lombok has to offer, then offer it.
