My wife and I are driving through Scotland in mid April and plan on spending two nights in Edinburgh which means we'll be there one full day at best. We'd like to see as much as we can and stay in a nice hotel in a convenient location in the city. A four star hotel would fit us well. Can you recommend the area we should be looking for that is safe and convenient for a quick visit to see the city? Also, what is the best way to see the city that we're not familiar with at all?
