New home in old building

It is as old as it seems, however it has many conforts of a modern house: a fridge, a toilet... that's enough for the basic needs I guess.
Couldn't fit a bed through the staircase (I'm occupying both floors with windows), but I hope the wonders of swedish furniture design will solve all my problems soon.
Windows don't have double-glass, which worries me a bit because winters are supposed to be cold around here... i thought... someone told me today that it doesn't snow as often as in Paris... I'm not convinced. Well, weather has been quite warm for the moment.
