I would really recommend staying with Tom, he is such a nice host! The price is decent and comes with great value. All the information about the flat published on this site is 100% accurate.
Tom responded to all of my messages. We announced him about our arrival time in advance and although it was a working day, he still decided to stay at home to welcome us. He was very helpful by aiding us with our luggages and showing all the amenities, including the washing machine. We got a small problem with the shower and Tom fixed it immediately. He respected our own privacy and was so kind to look after our stuffs while we were travelling. Besides, I encountered several student problems and Tom was free to offer solutions; we had short but interesting chats.
The entire flat is sparkling clean, from the living room and kitchen to the bathroom and our bedroom. The bed is spacious for 2 people; all the beddings were sufficiently provided for guests. He does have towels in case you forget.
Location is pretty convenient for bus users (1-2 minutes walk). As for the train, Tom's flat is less than 10 minutes walk and more suitable for those without too many suitcases (like us, as you will walk through a small yard covered with pebbles and climb up a little bit!). Just be careful not to mistake Catford and Catford Bridge stations (tip: Catford is closer to the flat).
Last but not least, thank you Tom for the great time! We look forward to staying in your flat if we ever visit London again (and as long as the room is available)!
