Questions
Questions About Sumyca
What does Sumyca charge?
AirROI does not publish or estimate any single company's fee, so ask Sumyca for its rate card in writing, and what it covers.
How do I contact Sumyca?
Sumyca's Airbnb host profile lists its homes and reviews and takes messages through Airbnb.
Where does this data come from?
AirROI counts the active Airbnb listings run from Sumyca's public host accounts, as host or co-host, over the 12 months to September 2026. The counts cover Airbnb only, so its full portfolio may be larger.
About the data
About This Data
Every figure comes from AirROI's data on active Airbnb listings over the 12 months to September 2026: listings open to bookings through the year, run by the company as host or as co-host on the owner's account. The company's Airbnb accounts with 5 or more listings are joined by name, so smaller accounts may be missing and the counts are a floor; homes listed only on other sites are not counted. Nothing is self-reported. Profiles are refreshed every quarter, next in January 2027.
