My girl friends & I are planning on spending 4 days/3 nights in Rome in early July. (We're visiting England for 2 weeks & decided to take a short trip to Rome) We're still in the process of looking for accommodations (either a hostel or a convent - thought it'd be an interesting choice) Anyway, in such a short period of time, can you please suggest some MUST SEE places? Also, we're on a budget. How much would you suggest us to set aside for this side trip to Rome? (Btw, we're from Canada) Thanks!
