A brief of idea

An Airbnb host can be the perfect business for you to start because you can be available at the odd hours when other unit owners are usually working, and cannot accommodate their guests. That is where you can help them since you may have more flexibility with your schedule.
This business idea would involve working with the unit owners to provide a great guest experience for their bookings. Services could include clean-up, laundry, amenities replenishing, key management and other guest satisfaction tasks. A per unit or per-visit charge could be applied to your clients. If you live in a big city, this would be a great idea to consider as there will usually be a lot of Airbnb rentals to target.
