Noticed something, when I look for a room using my Desktop, the housing page shows only 8 hotels for my search.

If I use my smartphone, same dates at the same time I searched with my Desktop, it shows 12 hotels for my search.

Why the discrepancy?

One thing I've found about the Q-Rooms portal is that refreshing the page or clicking search doesn't always actually re-run your search. One platform may have old results. 

Two things I've found that do force it to refresh are turning the "Show only available hotels" option off and back on again quickly, or changing the number of occupants from 1 to 2 or vice versa and searching again.
