Publishing on dreamo.ch is included in the SwissMLS subscription, which gives you access to the entire distribution network.

To activate Top Listing for your properties, log in to your dreamo CRM, select the individual object you want to feature, then navigate to the Publishing section within that object and toggle the Top Listing option.
Note: The Top Listing option will only appear if the object is toggled to be published on dreamo.
