This was my second stay at Julie and Valentin's house. They couldn't be nicer people, they're respectful of space and privacy, and their home is very welcoming.
The house is on a residential street, but it's a very short walk to restaurants, grocery stores, and bus stops. It's a few blocks from the Kilburn Underground stop on the Jubilee line, and the neighborhood felt safe to walk through late at night.
Highly recommended!
