Guess what? It has now been confirmed that our oven doesn't work. We were told by the landlord that it was user error, that Italian ovens are different then American. Ha!! I also found out where the heat comes from. It runs through the ceilings. So I guess the heat is on, as we've been quite comfortable with the temperatures in the 50's. Still haven't tried to use the foot. We're going with the theory of the longer I can stay off it the faster it will heal.
