Helena was very nice and helpful, so it was easy to find her apartment. Moreover, I arrived later than expected. Helena was waiting for me.
Helena is a lovely and generous host. She even provides you with shampoo, douche gel and even home shoes!
Very nice fully equipped and shared with the owners kitchen. Helena took care of me, brought me yogurts for breakfast and plenty of choice for coffee and tea. We talked a lot about many interesting things. Unfortunately I had no time to exchange more.
The bed was about 180 large bed. Big wardrobe, space to study. Big room! Otherwise, one of two nights it was a bit noisy from the street and from the neighbour, but the weather was too nice, so nobody slept but enjoyed each moment. I am convinced you will fully enjoy your stay at Helena's apartment.
Yes, it's 10 walking minutes from the underground, which brings you directly to the Green garden station with Buckingham Palace, Bond street - shopping mile Oxford street; and overground (easy to get to the London City Airport). A lot of shops, bars and restaurants are near the apartment.
I didn't manage to see, as everybody says, a huge and beautiful park Hampsted Heath, with its Parliament hill and amazing view over London.
