Great flat/home base for a couple of weeks, I have no complaints. Everything seemed clean and it's a nice place. It was nice to have a washer. I also thought having lots of books and even weights was a nice touch. The room is really spacious, lots of natural light and the bed is comfortable.
The location is excellent. Close to multiple buses and tube lines that go into central London within 30 minutes. But out of the way enough that it's very quiet at night, and not too loud during the day either. Felt pretty safe and all that. Right next to North End Road, which has tons of great food options, including vegan.
Although we did not meet because Olga was away, communication was good whenever I had questions and she seemed nice.
