The stay with my girlfriend at Hoang's place was very comfortable. The flat was easy to reach with the metro and it is located in a nice district right next to a beautiful park. The room was big and clean. We have met Hoang only very shortly on some evenings, but he was very friendly and sympathetic. He even provided us with a french SIM card with internet to help us get around in the city. I would definitely recommend staying at his flat! (:
