Trevi fountain, or Fontana di Trevi as it is called in Italian, is onw of the top sights in Rome and was just steps away from our hotel. It is beautiful day and night, and always packed with people. As there are tourists and its a romantic location, there are also plenty of people selling roses and other things. Based on my experienced, there’s the least people early in the morning.
On the side of the Trevi, there is also a beautiful catholic church.
