I had a great stay. The place was clean and provided basic things like tea coffee milk and bread. I stayed in early December and despite the cold I still managed to stay warm with the heater and plenty of blankets in my room.
The place is really close to Lee station with trains that run into central London every 30 minutes. Use the Citymapper app and you can be in central London by train in about half an hour (including the walk to the station).
Really great value for money.
