It depends on the market you're aiming for.

A younger, lone traveller staying 2-3 nights is probably going to be out doing things in the day, and in the evening. And they won't have much luggage either.

Elderly travellers might not have the same level of energy; they might prefer to spend a few hours quietly relaxing with a book. And they might want an armchair per person, rather than sitting on the bed to read.

Business travellers might need somewhere to set up a laptop and work from, power, decent internet connectivity, and someplace they can iron some shirts.

Longer-term travellers (e.g. someone visiting a city to supervise like the building of a warehouse) will have more luggage, and they'll want to make themselves a bit more at home - they won't be out on the town every night for a month. They're more likely to use the hotel gym.

For some people, holidays are all about relaxing and doing things at a leisurely pace. Perhaps they want to spend the morning sitting on a balcony reading the newspaper - if you have a balcony.

For couples on honeymoon, they might want a nice room with a great bed.

Families might have two children and two adults sharing a room, with the children going to bed earlier and the adults sorta hanging out nearby; in this market, the hotel room sofa might fold out into two beds suitable for under-10s.

And of course, if you want to target all of these markets at the same time you end up with the classic cluttered hotel room with wardrobe, desk, desk chair, armchair, bedside tables, reading lamp, ironing board, TV, etc etc etc

For me, in addition to a clean comfortable bed, and a good shower (I don't like a deep bathtub I need to step into), I like having a desk and at least a comfortable chair (ideally a sofa).

Of course, now we're getting into a fair fit of space in a dense city.
