I may be biased, but I would have to say that O’Neill Library is the most *surprisingly* cozy & welcoming. The facade is new brutalism, but my supportive & kind library helpers and the comfy chairs give this building a warm heart. I’m more familiar with academic buildings, most of which are more grand than cozy, with the exception of the libraries, of course. I’m not as familiar with the residence halls. Maybe you all can rank them?
