It is advisable to think twice whether you wanns stay in a old building and old apartment on the 4th or 5th floor without elevator. The view ist not nice at all, since you only see an ugly courtyard, lots of pigeons and only buildings and walls. The sun barerly shines into the apartment. I stayed from 15th to 20th of October when days are still warm, around 23 degrees and above, and nights are cold around 11, 12 degrees and during two nights only 8, 9 degrees. They only switched on the heating very low and for a little time, bc there wasn't much petroleum left. There is only once AC, in the living room. So the bed room and kitchen remain cold and since the warm air stays up, when you are sitting or lying it's still cold. ....
