We liked the stay at Wen's place especially because of the very quiet nights	and our good sleep. The kitchen equipment is a bit old fashioned but the air conditioning is the best we've ever seen. Wen's hospitality is amazing although we had absolute privacy. It's a 800 m walk to Croydon station. You should calculate 1h to get to city center by train. Good to know: there are direct train connections to the airport from Croydon without change. You can stay on the train which continues as another line. Google maps is reliable on public transport here.
