DD had a loft bed - the one that looked like the cottage. There is a "boy's version" that looks like a castle. It was a good bed for a younger child because it was so enclosed. Only when she got older did one of her friends how to jump off of the roof
That loft bed lasted few years but eventually she got too tall to be under the loft part. We kept the bed for even a few years after that and it became increasingly difficult to deal with. Like a bunk bed, making the bed is nearly impossible and DD would lose all sorts of things under the mattress. Trying to kiss her good night was nearly impossible. Snuggling in bed had to be in our bed because trying to get up into her loft bed was hazardous for us.
And loft beds are visually imposing. Whatever wall it is on will "come at you" at least 4 feet. Imagine visually reducing the room by the width of the bed.
Now if you're considering a more open loft bed, do be careful about safety. One of our older children broke her arm "falling" off the top bunk. Kids really do get hurt by falling off of there. And if the room has a ceiling fan, do be careful about that, too. BTW, it is hotter up there by the ceiling.
Loft beds come in different heights. Personally, I'd do a raised bed to have extra storage underneath, thus eliminating the need for a dresser. Or I'd re-organize the closet so the dresser items could go in there. The tallest beds - meant for teens and college students - may be too high for a littler kid. I'd purposely stay away from those beds that have the little door that opens to deep storage. That might be fine for an older kid who is stashing their ski equipment but my younger DD would just stuff items in there while cleaning her room - including food or candy she would sneak into her room. Cleaning out a cabinet like that would be nearly impossible.
