“It’s holiday themed and one of the big draws is the majority of the homes on the private street open so people are able to tour inside the homes and see what it’s like living on the street,” he said.

Which Marybeth Nevulis and her friends couldn’t get enough of.

“It’s really fascinating and we love seeing all the old houses and stuff,” she said.

She described the houses found in Elfreth’s Alley as “very quaint, they’re small, petite. A lot of history in them. Very interesting furniture.”

And all decorated for Christmas.
