After reading some of the reviews I was a bit skeptical, but the place was actually good!
Yes, it’s small, but it had all the amenities and it was clean. The location is nearly perfect—easily walkable to the nearby Tube station, also a couple of bus lines are running around. The neighborhood is very lively and diverse, but I never felt unsafe. Plenty of international places to dine. My only small issue was with some neighbors—the house is really old, the internal soundproof isn’t very good and all the flats are rented out, so you might get unlucky with your neighbors, like I did one night, but other time it was peaceful and quiet, also no noise from the streets (but my flat faced the backyard).
All in all, I think it’s a good value for one person, for a couple of days.
