Process is intuitive, screens are graphically clean, customer service is very responsive. You never feel abandoned and stuck. I am a sole proprietor, and my time is valuable. Our paper calendar and excel system was costing me time and was becoming confusing. I was worried about a double-booking (every innkeeper's nightmare). Since using OwnerRez, I've "found" about 10 hours a week. The "book it now" button makes it easy for folks to make a reservation, so we've seen an increase in bookings.
Perfect for accommodation that wants to start easy, and grow into more features. Its all there.
Nothing to dislike! I would be making something up!
