Me and my family stayed at Jazzi when we're in Bromo. It's a clean room with clean bathroom, and a big bed. He also offered extra bed when we need it. The official was very helpful, they helped us arranged a Bromo tour, also arranged a rent car from Batu Malang to Bromo and back to Surabaya, and also arranged breakfast for us. He also very responsive to answer all my questions before I decided to book his place. jazzy homestay is recommended when you need accommodation in Bromo.
