Which two cities does the Trenhotel Lusitania (hotel train) run between?

The Trenhotel Lusitania runs from Lisbon to Madrid (or Madrid to Lisbon). The train leaves in the afternoon and arrives in the other capital in the late morning. Unfortunately, due to covid, this overnight train route has been suspended and now there is not a nonstop connection between Lisbon and Madrid.

The hotel train offers a 3-course dinner for those who are hungry and breakfast. The few reviews suggest that earplugs are probably a great idea as the noises on the track can make it hard for some to sleep.
