Depending on what you do with the interior, they can actually be great apartments.
Much quieter than street facing, put a nice little courtyard in the center.. etc.
I once worked in an office where all the windows face a plain interior courtyard. It was terrible as nothing ever moved and you could only see the ground, more windows, and the sky.
Many apartments in Europe are designed this way. The interior courtyard in most of them just contains trash cans and residents' bicycles or mopeds. They're not especially interesting views. But people don't generally move to cities for exciting views out their window, the other benefits outweigh it.
