Dear Pete,
Congrats! Our city is really very beautiful, you should visit many places there and sure I am gonna help you.
At first, you need to find a bus stetion, it is the best way of getting to the centre. So, weather forecast shows us that the weather wont be comfortable. I d recommend you to take warm clothes. As well, I wanna to introduce you some hictorical places of our city. There are a museum of WW2 and, sure, Red Square too.
With love,
Kristijan.
