A decent place to stay, especially if you're looking to visit London. Less than 10 minutes from the tube station (around 40 minutes to central London however) in a quiet area. The amenities in the room are nice (fridge, kettle, toaster), and the bed is double. The host is extremely nice and friendly.
However, there are certain aspects that you might want to consider before renting. Cleanliness is not at its best, the walls between rooms are relatively thin and the ladder from the loft room will constantly block the entrance to your room. The toilet is next to the room, meaning that you will constantly hear when someone is using it. The sink in the toilet is tiny and very hard to use for anything other than washing your hands. The shower is situated downstairs, adjacent to the host's studio, which also acts as a kitchen, so you will not be able to take a shower whenever you want.
During my stay, there were at least 5 viewings for the room that I was occupying, with no more than a few hours notice in each case, which I tried to be understanding about in the beginning. However, it can definitely prove inconvenient and uncomfortable.
