Choose your base before choosing your stops
Write your actual hotel address at the top of the plan. A neighborhood label is not enough: the station entrance, luggage arrangements and the walk back at night all affect the day. Before booking a cheaper room farther away, compare the total journey to your first and last planned stops. Decide which matters more to you: fewer transfers, a quieter evening, or being near a particular museum. A solo visitor can change pace easily, but carrying every decision into the street becomes tiring.
Keep arrival and departure outside these three full days. If your flight arrives on Day 1, replace that morning with travel, baggage drop and a meal. Do not compress the missing visits into the evening. Save your accommodation address and a screenshot of the route back before heading out; a phone battery problem should not also become a navigation problem.
