As a resident of Old Town Tallinn, I get a lot of friends coming in for a day or two on cruise or holiday visits. I always take them on a walking tour of the Old Town and even if they only have 4 hours to spare, I make them trudge up the narrow limestone staircase of Oleviste Kirik. Even if the walk up and down can be intimidating or tiresome, the views are worth it. It is fun to point out the fortress walls and towers, look towards the port and beyond and point out other places of interest. You can take great photos and see early gothic construction from the inside out.
