That works for me. In the last months of collecting data for my PhD thesis, I pretty much lived in the lab. This was basically biochemistry, so there was lots of "do this, wait some hours, do that, wait some hours, ...".

So I just napped when I could. At night, on the couch in the break room. During the day, on the cot off the women's restroom. And conveniently, there was a shower for staff who cared for research animals.

Now, living in a small apartment, my ~12 m^2 room includes desk, bed and storage.
