It's a really nice and cozy flat with everything you need for a stay in London. The sourrounding ist quiet and you can reach the northern line for underground transportation in about 10 minutes by walking. There are few supermarkets nearby opened till late in the evening, so you can get food and drinks there.
The contact to the renter and his agent was excellent and they answer every question really fast.
I'd absolutely recommend this flat for everyone who wants to visit London.
