I and my friend booked this place for an event in Islington. Violaine's place was very close to the place of the event. And there are many restaurants, pubs, cafes and supermarkets, very useful for staying. And very good access to bus and underground stations.
The rooms are very clean and comfortable, and airy. It's feel like heaven for the Japanese from hellish summer. A bit noisy outside of midnight on weekend but we didn't mind about so much.
I met Violaine a short while, but she was so kindly and so powerful.
I think staying this place is better than expensive small London's ordinary hotels. Highly recommend!
