2.5 week trip budget question

hey everyone! i’m going to italy pretty soon for the second time (first time was for a 2 week study abroad, this trip is me and my partner). this is the longest trip we’ll probably ever take and i want it to go as smoothly as possible. the total cost for hotels is estimated to be €1830 and i’m planning a budget of at least €100/day for food, so around €1700. flights and train tickets are already booked as are all of the activities. our itinerary looks like this: Rome (4 nights) Naples (3 nights) Florence (3 nights) Venice (3 nights) Milan (3 nights)

for accommodations and food and public transportation i’m expecting that €4000 will cover it. does the budget i have planned seem feasible or am i being unrealistic? i’m really anxious when it comes to money and i want to make sure i have enough to have a good time. any feedback is appreciated, thanks!
