Generally speaking a good accommodation for solo travellers as the neighborhood seemed quite safe to me. It is about a 10 minute walk away from the Oval underground station and from there it takes about 20 minutes to the centre of London. Geoff is a nice host who welcomed me as I arrived. He also offers breakfast to an affordable price which is good value for money.
Concerning the room, it is smaller than I have expected but sufficient if you only travel with carry-on bags.
To sum it up, good value for money and only an underground or bus ride away from central London.
