I had a really great time here! It was exactly as described, with a shared kitchen and bathroom and someone else in the other room, but neither of these bothered me at all and there's a lock on the door with a code. Like others said, great value for that location. It had a bed, couch, TV, closet, and dresser but I pack pretty light so didn't need a lot of storage space. There were many cool restaurants and pubs in any direction, and a tube stop was nearby which allowed me to venture out into the city.
The host was communicative and patient while I figured out how to use the tube from the airport and waited while I went the wrong way a few times lol.
It was a great place to stay for my first trip to London and it was nice to stay in a real neighborhood instead of a hotel. You can easily explore the city, but I would certainly recommend checking out the local spots in that immediate area as well if you have time.
