We never got to meet Maria but out mail contact was great Maria answered all our questions with in a couple of hours.
The house was very clean and we enjoyed the neighbourhood , we felt very safe walking from the subway to the house in the evenings.
Maria has lot's of information in the house over London and getting around the city .
We enjoyed our stay so much that we will most definitely be going back and were letting everyone know this is the place to stay if your visiting London.
