Facebooker Pham Tra posted photos of a homestay with modern-equipped rooms on her Facebook page.
She said her homestay was only a two-minute walk from My Dinh Stadium where Blackpink will perform for the first time as part of their current Born Pink world tour.
Facebook user Thai Thi Hang offered their homestay, just a 10-minute drive away from My Dinh Stadium for VND850,000 (USD36.12) a night, including free pick-up service.
Many other Facebook users have been advertising their services on social media, including combo packages for those who live far from Hanoi but wish to watch Blackpink shows.
Hoang Hoai from Thai Binh Province, around 100 kilometres from Hanoi, said: "I have been a fan of Blackpink for a long time. I’m so happy that they’ll perform at My Dinh Stadium next month. I'm also hunting for tickets and looking for cheap homestays to book in advance.”
Bui Thanh Tu, marketing director of travel company BestPrice, said the next concert tour of Blackpink in Hanoi is expected to be a major event, with fans from surrounding areas set to flock to the concerts.
Blackpink were formed in 2016 by YG Entertainment with four members Jisoo, Lisa, Rose and Jennie. The group quickly became one of the most popular girl groups in the world.
