London is a big city, very spread out, so unless you book a place right in the city city, you will always be a few metro stops away from everything, which is why Tom's listing is great, you are smack bang in the middle of two important metro lines, so if you wanted to go somewhere in Campden, you are only a 20 min metro ride away
Or if you're going to catch a play in the theatre district, you are just a 10-12 min metro ride away
The advantage about not staying right in the city city, is the peace and quite at night time so after exploring all day you know you will get a restful sleep
The place itself, is decked out with everything you need, including a washing machine if like me you travel a lot and need to do some laundry, has one of those great new coffee machines ( sorry Tom I used up all your coffee pods ) and the kitchen is fully equipped, has 2 bathrooms which is a bonus, and in summer enjoy the little outdoor entertaining area
I will be back
