The 28-year-old put the Oranje ahead on the stroke of half time but two second-half goals from the Balkans saw the score overturned in the visitors' favour and inflict a surprise loss on Bert van Marwijk's side.
Nonetheless, Van Persie believes that Bulgaria provided Netherlands with credible competition ahead of the European Championship, and that losing now rather than at this summer's tournament was consolation.
"It is better that this happens now rather than in two weeks," the Arsenal striker told De Telegraaf.

Although he has played most of his football for Arsenal as a centre forward, Van Persie was used on the wing by Van Marwijk to accommodate Klaas-Jan Huntelaar through the middle.
"The coach picks the team and we just need to play," he continued. "It was nice to score and indeed I did so when I emerged as a striker."
The Gunners captain has been heavily linked with a transfer away from the Emirates Stadium during the close season, but again he refused to shed light over his future.
"It is true that I have drunk a cup of coffee with Mr. [Arsene] Wenger. But what was discussed stays between us," he concluded.
