Actually I would like to describe the place a bit more because it was not obvious from the website nor other comments: this is no hotel nor b&b, these are 5 rooms to let, with two bathrooms and a small kitchenet. The owner welcomes you at arrival and that's it, you are independent for the rest of your stay. Everything very nice and clean, decorated with taste. All newly refurbished, in particular the very neat bathrooms. The kitchenet very practical for having a quick meal if you do not want to spend money. Good value for money.
Some equipments not in use (tv in one room) but I did not call the owner to tell him (my fault). Two bathrooms is not enough in the morning if all rooms are full and all wanting to go there at the same time (happened only once in 5 days). 15 minutes walk to the nearest tube station, but that's ok. Not the most glamorous part of London (rather miserable actually, and quite "coloured") but it did not bother us because we don't mind this sort of things.
