I haven’t heard great things about Guesty for Pros, and I wasn’t impressed when I did a demo with them either.
I use Hostaway now however and highly recommend them. Customer service is super easy to get in contact with. Their system is great and will definitely be good to use as you scale up. Their income reports are great.
Really easy to export constant changes to Airbnb, VRBO, direct site. Booking .com is easy to export to initially, but after the initial export updates must be made to the listing manually (updates to the listing other than pricing updates that is). For ourselves, we don’t care about that channel anyways so doesn’t matter to us.
A few weeks ago we exported all of our listings to Google vacations. It took literally a few clicks and we were done. Within a few weeks we got about 5 bookings. Plus, Google Vacations directs customers to your direct booking site to complete bookings. So you get extra exposure to your site, and you get to set all your own policies.
