Yes house is in the old town of Lausanne and you can not really have an elevator in this aria. Its in the forth floor and Babak would not complain about calm and cosy neighborhood.
I am surprised by the comment about blankets and sheets, because I make sure its all new clean and comfortable. It is not New brand every time, but still clean and cosy.
Hope stay was anyway good for you, especially with rain every day of your stay.
