The flat itself gives you a home away from home feel.
The ups:
Stunning decoration, comfortable furniture, quit nice neighbourhood, very close to tube station, few shops/cafés/restaurants at your doorstep. The host is very flexible regarding chick in/ check out time.
The downs:
You will haver to get a taxi if you stay out until after the tube stations have closed, having a shower is quit difficult.

In general, I really recommend this flat as the host is very helpful and flexible and the flat itself felt like home!

This can well be my London home as I tend to visit a lot!
