Cheng's house is in a pleasant residential street. The house is clean and tidy, and the double room is great,with somewhere to sit and hang clothes.
Cheng was extremely welcoming and even offered me an ice cream on arrival after a hot drive, and Water Melon whilst chatting during the evening.
This is a great base for exploring London, and Croydon itself is very good for food @Boxpark.
Can't fault the experience really. I'd definately stay again.
