As as renter, I much prefer living upstairs. Two reasons: one, I don’t want the clomping of neighbors overhead, and two, I like to open my windows at night, but I’ll only do it if my bedrooms are upstairs (and not located on the veranda, obviously). Yes, moving furniture is a pain, but you only do it once, and the benefits of living upstairs are many.
It sounds like this deal is potentially a good one! Good on you for doing the research.
