Renting a car would not be a good idea. As others mentioned, public transit is excellent so you’d be making it harder in many ways (parking, traffic) but also driving in another country can be so unexpectedly different in minor but important ways. Different rules of the road, and driving on the left side just reverses so many instincts in where to look in the road.

I’ve traveled around a lot. The only times I’ve really been glad to have a car outside the US was in Oman (public transit is terrible) and to a much lesser extent, Norway (visiting family in smaller towns)
