I'm a big fan of this flat and highly recommend it for a long-term stay. Highlights include the balcony (with a sweet view), fast wifi, smart TV and a decent washer-dryer.
Best part is the location - esp for first timers to London. Quick walk to the Notting Hill Gate station where you can catch the Central or the Circle/District lines. Walkable to bars, restaurants, etc. and the Portobello Market every Saturday.
