Ash was a great host. The accomodation is simple but cosy. The location doesn't look like good but it is. The neighborhood is good and quiet. The underground stations aren't so close but there are many buses stop near and it's so easy to take a bus and tube as well. I think the wi-fi was be a little better cause the connection was very unstable and always losing the connection. I had to talk a few times with Ash and all the time he had solved it to me.
Anyway, London is very expensive and this accomodation worth the price. I recommend!
