I think it depends on the size of the apartment. I would like to have a large apartment with many rooms and high ceilings. Possibly, if the rooms are a bit smaller, suspended ceilings at 2.8m. In studio apartments, I find a sleeping loft cool – but only for the younger generation. If the main tenants are seen as students, then yes to a loft bed. Otherwise, I would possibly line the last meter to the ceiling with built-in cabinets, at least on one side – as storage space for things that are not used very often. However, I would always weigh whether the construction and maintenance effort is really worth it. In an area with low rents, I would furnish the apartments rather cheaply and simply. If the tenant wants a loft bed, they can gladly install it themselves. In student apartments in high-priced locations, good furnishings including a loft bed would certainly be an option, which would also affect the rent. For apartments, I would generally always calculate how much the conversion costs spread over 20, 30 years – and whether that really results in higher monthly payments. This is also how the decision against a balcony in a rental apartment was made for us. It does not pay off.
