House use is a function in Mews to allow to block a space for a certain time without taking it out of the day inventory.
The usual uses of it would be:
setting up a showroom
If you would like to run a report to see the amount of house uses over an extended period of time, go to Occupancy directly from the Dashboard or Settings > Reservations > Occupancy
Only the date filters are relevant for this search. Once you've entered the desired dates, click OK and Export. Once the export is ready, Mews will notify you, download it and open it in Excel.
You can then go to the House use tab to make your analysis.
