The 76-year-old former leader has not been seen in public since a February military coup removed her from office.
The BBC’s interview with military spokesman Major General Zaw Min Tun comes after the release of US journalist Danny Fenster who had been sentenced to 11 years in prison.
Dozens of journalists and thousands of people have been held since the coup.
Maj Gen Zaw Min Tun said Ms Suu Kyi was being kept well in detention.
“I mean we let her live with her own people in a house although she is under house arrest,” he said. “We try our best for her, what she wants or whatever she wants to eat.”
She has appeared in court but little has been seen or heard from her aside from these brief appearances.
The UN has called for her release.
Speaking to the BBC, Maj Gen Zaw Min Tun also said that authorities intended to release US journalist Danny Fenster.
Mr Fenster was released on Monday, just days after he was sentenced to 11 years in prison for breaching immigration law, unlawful association and encouraging dissent against the military.
He was also set to stand trial on further charges of sedition and terrorism.
Last month, Myanmar’s government said it will free more than 5,000 prisoners jailed for protesting against the coup.
At least 7,291 people have been arrested, charged or sentenced following the coup, according to the Assistance Association for Political Prisoners.
