Need help picking short term rental software; STR calendars

[Ken Dillard]

I am buying my first short term rental property and first platform will be AirBnB. Many people are advising using multiple STR platforms to rent through (i.e. also use Homeaway, Flipkey, etc).

How are you managing your availability calendar on different platforms?

Seems like a pain and opportunity for double booking if I have to go to multiple OTAs and block dates when a booking occurs.  I have been looking at software like Xotelia or AirGMS.

Thanks for any guidance!
