Rosemary is a great host! Very friendly and flexible with check in, which was much appreciated. The place is comfortable and warm. Breakfast was cereal, toast, spreads, tea, and coffee which was great! The walk to the Colindale underground station is ~10 minutes walking, very easy. It’s a bit away from the city center (~20-30 min on the tube) but it was so easy that it wasn’t really a problem for us.
