The star prospect pointed out the facilities, coaching staff and players as among the reasons he likes UNC.
"It's North Carolina," Tarczewski said. "It's amazing. I didn't really know what to expect from the school itself, but it's a gorgeous school and I think the academic opportunities are really great there. I just had a really fun time."
"All the players there are really high class players and they are great kids off the court, too, which is something that you look for," he added. "I really liked the coaching staff."
Did the visit meet expectations?
"They definitely met the expectations that I had," he said. "They probably surpassed them. I wasn't really sure what to expect. I had heard things about North Carolina from different people, but I didn't know what to expect. I think that I could do well there and like I said it's a great school."
While on campus, Tarczewski and his parents, who joined him on the trip, sat down with Roy Williams. Tarczewski walked away impressed with Williams' approach and demeanor.
"He's such a trustworthy guy," he said. "I like that he'll tell you how he feels, which is very important because if you go away to a school and you're away from you family you want people you can trust and are like family to you. I think he's a great guy and he's definitely someone that I could see me playing for."
North Carolina, which offered the No. 5 overall prospect in the 2012 class in mid-April, has made it clear the team is in search of an elite post prospect. The staff has prioritized Tarczewski and he said they made that clear.
"They really need a big guy and a lot of people know that," Tarczewski said. "I think I could definitely fit in there. I think they are just going to continue recruiting me how they have. They've done a really good job. They came in a little late, but they've done a really good job catching up."
Will the late arrival hurt UNC?
"A little bit," he said. "I've been pretty close with Kansas and a few other schools up to this point. So I already have feelings for some other schools, but I think they've done a really good job catching up and they are right there with everyone else."
One aspect of his visit that Tarczewski had further praise for was the time he spent with the team. He was with the players during one of the school's camps and had the opportunity to hang out with them off the court.
"They players there are really great on and off the court," he said. "It's some place you could go and have fun and not have to worry about all the emotional stuff that happens off the court."
Tyler Zeller was Tarczewski's player-host and the two ended up having quite a bit in common.
"I got to sit down and have lunch with him," he said. "He's a great kid. I really love how he plays. But I mean off the court he's a really good kid. Actually I'm thinking about going into business, but at first I wanted to go to engineering."
"It was funny he actually tried to go into engineering at first and switched over to business. We are kind of a lot alike and it was fun hanging out with him. He's a lot like me."
Tarczewski, who has already taken four unofficial visits to Kansas, said the two schools are comparable.
"They are both some of the best basketball programs in the country," he said. "It was really an honor to be there. To be honest they are a lot a like. They both have things that are really great about them and things that attract you to go there."
To go with his recent trips to Kansas and North Carolina, Tarczewski is also checking out Arizona this week. While those three got visits before July, he said he hasn't cut his list to those three.
"There are other schools involved," he added. "These are just the schools that I felt comfortable taking visits to at the time. I really like all three of these schools. I just wanted to diversify what I've seen and kind of look at the bigger picture."
With July coming up, Tarczewski is planning to put recruiting behind him until the big month is over. Then he'll begin thinking about making his college choice.
"I'm trying not to think about it too much. But I'd like to get to this decision over sooner than later. I'm probably going to wait until after July before anything is final. I'm definitely going to start thinking about it more and more as the summer goes on."
