The flat is located perfectly, which is why I think it gets so little love from the owners. I mean, it has SO much potential, but everything that is broken just gets left that way, sadly. It would not cost much to replace simple IKEA furniture that is broken and unsafe and the flat could really use it. The creepy door in the bedroom was also a very scary surprise, maybe rather inform your tennants before the stay instead!
On the plus side, the lady who greeted us (Daiva) was the nicest person I have met in a long time, so helpful and friendly. The noise from the tube is not an issue at all in my opinion! The flat is big for London standards, there is a tesco just up the street as well.
I would love to stay here again for my next london visit IF the broken furniture/lamps/window and so on gets fixed. As I said, the place is good it just needs a little bit of love. :)
