You'll be sharing the place with me, but I'm often staying at my partner's or working. It's a 10 minute walk from Oval and Kennington Tube stations on the Northern Line. There are also frequent busses 2 blocks away that take you to Victoria/Vauxhall.
There are great local pubs around. It's clean. Your room has a comfortable bed. The lounge room is separate from the room so it's great if you want to duck off to sleep early.
