Albon has managed to score top-six finishes in every race so far for Red Bull, leaving the energy drink squad to make the call after the US Grand Prix to retain him for a full season next year.
Speaking about the decision, Verstappen said: “He’s a nice guy. I think for him, the last 12 months have been a bit of a rollercoaster.
“Of course, he’s very laid back, very relaxed and people like him in the team. He’s easy-going, which I think helps.
"He’s quick, he’s doing his job, he’s getting the points. I think it was the smartest way of continuing.”
Albon spoke on Thursday about his "short" phone-call with Dr Helmut Marko, who informed him that he had the seat for the 2019 season.
The Thai-British driver says he wasn't sure when the decision was going to be made, but affirmed that his primary focus was on the race weekends.
"I didn't know when the decision was going to be made," he said. "For me, it was thinking about the races that I had and making sure I was happy with how I was progressing.
"I think that was an important thing, to show that I am making steps forward. In terms of when I was going to get the call, I knew it was going to happen, but I wasn't stressed when.
"As I said before many times, I was just focused on the job at hand."
