Although I did not manage to meet Melvin during my stay, he was still very much present through text and calls. He was very friendly and communicative over the phone. The house was spotless and the bed was comfortable. Heating was also sufficient during this cold winter. Location wise, there were a lot of places to get your basics necessities along the high street which was pretty convenient. However, I did find it expensive to travel to London city centre every day; wasn't expecting the public transport to cost that much as a traveller from Singapore haha.
For transparency, I have to disclose that I didn't have access to hot water in the shower for an entire day. I don't blame Melvin as apparently one of the other guests in the house had turned off the boiler at the switch for some reason. After the issue had been resolved, the boiler had been turned it off again for the second time. At this point, Melvin was out of the house so he couldn't turn it back on by himself. However, he did help guide me over the phone on how to turn it back on again.
Melvin was very apologetic about the incident and I can tell that he holds a high standard of hosting for himself. Nonetheless, would definitely recommend this place for someone who needs an affordable and clean place to stay in London.
