I stayed at Lorena's appartment for a longer weekend with my parents and my brother.
It is located near to the center, in 5 minutes you will reach the next bus stop and then it's 10 minutes to the center (Liverpool Street). We felt safe in the neighbourhood.
The appartment is great! Very clean and stylish furnished. In the night it was a bit noisy (with open window), but that's city life!
Lorena was very nice, helpful and courteous! Check-in and Check-out were easy, though we arrived very early and left in the night. Communication also was super, Lorena answered quickly and gave us really nice advices where to go and eat in the neighbourhood.
I would definitely recommend stying at Lorena's appartment! :)
