It should be noted that Aragorn also has superb stealth skills as all Rangers of the North, even Rangers of Ithilien (who move ,,marvelously fast" and ,,vanishing almost in the twinkle of an eye" no matter rocks or trees and greenery in the wild or shadows of night, also we're told that Aragorn observed Frodo and other hobbits when they approached Bree in full daylight, unseen and the hobbits are after the elves most stealthy creatures :):)), the rangers no matter northern or southern ones are skilled in sneaking (sometimes they can move crouching with ease), tracking, survival in the wild, stealth tactics, ambush, reconnaisance, archery. Rangers of Ithilien were sort of a ,,special forces" of Gondor in it's armies. Dunedain (with strong blood of Numenoreans of whom all rangers seems to come from) also have keen senses. Then there is an advantage that they can speak in elven tongue which would allow to communicate and pass orders without dangers of enemy overhearing. While place of a fight is in the city Aragorn could also mingle into the crowd. Also Tower Guards are not any low level warriors they are the elite, it's an honour to serve in the Citadel so they choose the best, so Aragorn's men should have too some good skills. Beregond simple men-at-arms from the Third Company of Tower Guards was able to easily kill three of armed guards of Denethor at the tombs when the Steward wanted to burn himself and Faramir alive.

From the books it is also known that Aragorn already escaped traps laid by spies and agents of Sauron so he was always cautious when meeting strangers (it's good to mention that he was able to sneak into hobbit's room in the Prancing Pony Inn while they netered themslves and they noticed arleady when they close the door).
