Sami's apartment is absolutely stunning, exactly as described, if not better, and we were made to feel extremely welcome both by Sami himself in our text communications and by the doorman who was friendly and courteous.
The apartment is in a very quiet area but a very short walk from the delightful Angel area which if you don't know it is has an English small town feel despite being so close to the city.
If I ever want or need to stay in London again, I would love to go back to the same place.
