Melvin is very good guy and very responsive.
Although I had some issue and I had to cancel my trip and I hadn't had the chance to go to his place, but before I had to cancel the trip he helped me to organize everything and was keen that everything is going to be okay with me.
I was going to arrive late at night (around 3:00 am) and he organize something for me to check-in whenever I came to his place.
Also, when I had to cancel my trip, he help me to get more refund that airbnb refund system as I cancel the trip in the same day that I was going to arrive.
