Wales captain Ryan Jones said he was satisfied with his side's victory in Italy and the manner in which they built their 26-9 win in Rome.
"We have come into the game, with the weather atrocious, and Italy are a very tough team to break down," said Jones.
"They are big and physical and they were at home with a great record here, and it is a tough place to come.
"We knew what the challenge was and games like that are all about the arm wrestle and not breaking first."
Tries by centre Jonathan Davies and wing Alex Cuthbert, and points from the reliable boot of Leigh Halfpenny, secured the win at Stadio Olimpico.
Wales, who won the Grand Slam in 2012, have now won two of their three games so far in this season's championship, with a 30-22 defeat by Ireland and a 16-6 win over France preceding the victory in Italy.
This was Wales' sixth consecutive win over the Azzurri and a fourth successive away victory for Wales in the Championship - a feat they last achieved in 1979.
"It was about territory, putting the ball in the right areas and making sure the points count," added Jones.
"You have to build a win in places like this - it's a three-six-nine point game.
"The early points in the second half settled us down and we defended superbly and we managed to pull away in the end."
Wales now travel to face Scotland at Murrayfield in two weeks, knowing a win would see them host England in the final round of the tournament at the Millennium Stadium with a possible Six Nations title to play for.
Jones, who extended his record to 31-times as captain against the Azzurri, paid tribute to Wales' dominant scrum, the one area of the game that Italy traditionally seek to dominate.
Wales' front row of tight-head prop Adam Jones, hooker Richard Hibbard and loose-head prop Gethin Jenkins completely outmuscled their Italian opposite numbers at the scrum.
"Robin McBride [Wales forwards coach] is happy and there are six front rowers with big cheesy similes in [the dressing room] and they will be looking forward to the plaudits," said Jones.
"It's the second game in a row and it hasn't been pretty, but we have managed the win, with wonderful endeavour."
