I would suggest some more specific key, judging from taginfo something like
ref:<short name of the datasource>

if almost nothing is detached, it means most of the tags would be wrong. I
have been browsing the map, thank you for this, very convenient,
and while most of the features are located in the historic centre, there
are also many detached houses outside of the centre. The established tags
do not provide a method to add generic accomodation features, all main
classes are fairly specific: guest_house, apartment, chalet, hostel, hotel.
If the source data doesn't distinguish chalet from apartment it is
difficult, maybe you can guess it from aerial imagery.

I would go for "capacity", it is used 9999 times with tourism=* while
capacity:beds only 26 and beds 5739.
And because "posto letto" in a holiday apartment is not always a _bed_.
