PointsHound has a new promotion for bookings made and paid in other currencies than USD. PointsHound now supports 20 currencies in addition to the USD. You will also receive 500 bonus miles for your first booking. You can sign up for the service here.
Instead of cashback, you will receive your preferred airline miles for hotel bookings that you make using PointsHound. The service supports most major airline miles excluding United MileagePlus.

The price in USD is $159.53 and you would earn 500 American Airlines miles.
The Euro price is 114.53 and you would earn 450 American Airline miles + 500 bonus miles for the first non-USD booking.
It is surprising that the price in Euros is actually lower than the USD price.
Seems that the rates that PointsHound offers in Euros are competitive with those in USD. Note that signing up for PointsHound using the link here will support LoyaltyLobby.
