Do the rooms come with either a microwave or fridge?

Both

They did but now the hotel is under new owners so I have no idea what to expect

Yes some rooms have both others just a small refrigerator.

Yes they do some have both and some has just a fridge

Yes, the fridge is in room, but lastyear there microwave is located in the main lobby, unless they put them in rooms since then,

They have both.
