I continously had some bookings, although not as much as it used to be before the pandemic and most of them are "long term stays" ( 4 to 8 weeks).
Maybe interesting to know:
From The Netherlands there is a "test holiday" scheduled on 12 april to the Island of Rhodos.
There are strict conditions and protocols to join the trip for max 187 people.
Unfortunately information is only in Dutch:

We also had a "test conference" and a "test music event" recently.
They are all used for scientific purposes.
