If you noticed that everything is quite in Prague, there is a reason for it!
Today - 5th of July and tomorrow - the 6th of July are public holidays for the Czech Republic.
Please be aware that all of the shops bigger than 200 m2 will be closed. The transport comes on bigger intervals. You can use the wonderful occasion to walk around the city and see some of the places without too many people around. On the weekend everything will work again.
