You cannot ask for more than what you will get here. Leo and Veneranda are very friendly and helpful, and they maintain the entire house clean the whole time. They communicate very well with the guests as they have got years of experience in hosting through Airbnb. Unless you are trying to have a 3-days packed tour of London in which 3 minutes are too much to waste, otherwise the location is great, especially if you stay for long as it is close to good stores, restaurants and massive shopping malls.
You will get everything you need here, with helpful hosts answering any questions you have about London, a well-kept nice garden and maybe Veneranda's great cooking too (definitely try it if she offer you any).
A lot of guests stay for long period here, and come back again if they can - and you will understand why after you stay here.
