Had a great stay at Caz's place. She's a very welcoming and kind host. The room is small but cosy. The area is quiet generally and seems quite safe. You are about 7-8 minutes walk away from Catford and Catford Bridge stations where you can take the southeastern or the Thameslink into central London. It usually takes about 30-40 minutes and might require a switch to the underground but trains run relatively frequently. Respect the house rules and you should have a great stay!
