Well-appointed rooms/apartments (blurs the line) in a central location. Well-stocked kitchen with nice touches like coffee, sugar, olive oil, and a French press.
You may need to put up with street noise if you're on a low floor and want ventilation at night, but this is otherwise fantastic.
Deep bathtub, no noise from other tenants, recycling and composting facilities out back (a nice option to have), and responsive service.
