Hadi is a great host - when I arrived not only did he show me around (where places to eat are, bus stops, etc.), but also paid for the first bus ride since I didn't have coins (he prepared it in advance) and also gave me the EZ-link card, which is used for convenient payment of public transportation services. His relatives that are staying in the apartment are also helpful, nice and friendly. I spent good time there. By the way, anyone who likes Xbox will find it advantageous that they have an Xbox. I have played many games in Soccer with Hadi's youngest brother and had a lot of fun, even though I lost most of those games since his brother is really good at playing soccer.
The only disadvantage is that it takes around 50 minutes to get to the centre by the public transport.
I would strongly recommend it to anyone seeking a room to rent in Singapore.
