Very nice experience with Cristino and her sister Patricia,
I Spent One month at Cristiano's House and he was very nice and always keen to help you with any enquiry. The rooms was very nice and cosy as described at the post and very easy to get from the airport.
The place is quiet, clean and the shared bathroom is always in very good Conditions. At the kitchen you have all what you need to make a quick meal.
The Underground station is very close and there are buses In front of the flat which you can take to get to the centre within a direct and easy way.
I would definitely recommend the place to those travelers who are thinking to stay a few days in London and also those who are planning to stay more time until finding a long term accommodation like was my case.
