David and his family are very welcoming and helpful! Even though I didn't get to meet David, he sent me lots of information to get to their place before the trip just to ensure I am not lost. Their place is very clean and comfortable. The location is good, it's just 6min walk to Oval Train Station, which you can take the Northern Line to the city in around 20-25min. There is also a small grocery store nearby where you can buy some snacks too. I truly enjoy my stay here. Will definitely come back again! :D
