although no star rating is given here the industry talks about 'quality of services and facilities' to cover what I see as 'prestations':

1.3.1 Quality Assessment
There are five levels of quality ranging from One
to Five Stars. To obtain a higher Star rating a
progressively higher quality and range of services
and physical facilities should be provided across
all areas with particular emphasis in five key
areas - cleanliness, service, food, bedrooms and
bathrooms.
Research indicates that quality is of key importance
but visitors also expect the level of services and
range of facilities in hotels to increase at each Star
rating level.
1.3.2 Quality Terminology
We use phrases such as ‘good’, ‘very good’ etc. to
signify ascending levels of quality in broad terms
only. These standards indicate typical consumer
expectations of each star level. They are neither
prescriptive nor definitive because we recognise
the wide variety of quality elements that can be
included – for example, style, which can range from
traditional to minimalist.
1.3.3 What is Quality?
When we are assessing quality we take into account
the following:
Intrinsic quality – the inherent value of an item.
Condition – the maintenance and appearance of
an item. Is it fit for the purpose?
Physical and personal comfort – does the quality
of an item detract in any way from the comfort
of the user?
Attention to detail – the evident care taken to
ensure that the guest experience is special and
of the same high standards for all.
Guests’ choice and ease of use – the guest
experience is enhanced through choice – be it
the choice of beverages in his/her room or the
choice of room temperature. This is further
improved by how usable the
