Jim himself is a good and quick communicator and his place is nice, clean, uncluttered and comfortable.
It sits far enough away from the City centre to be peaceful and away from the madness, but at the same time, close enough to get to and from the heart of London in pretty quick time.
The walk from Streatham Station (National Rail) is perhaps a little over 10 mins, but all on fairly level ground (no massive hills or anything). Streatham High Road itself offers a diverse array of shops, eateries and a cinema, but you won't have to venture that far to pick up any essentials. There's a Sainsbury's Local, Chip Shop, Newsagents, Chinese and a very nice pub (The Furzedown - I recommend the Chicken Pesto Pasta) just a couple of minutes away, on Mitcham Lane.
All in all, the place was ideal for my needs and if I'm ever looking for somewhere to stay for a Theatre weekend again, I'll certainly be checking the availability of Jim's place.
