I love my studio, the skylights the bath the space. You'll love the location more than anything. No more than a 5 minute walk from Paddington Station, and really close to Little Venice and Hyde Park. You'll feel at home, comfortable, relaxed.
For W2 it's pretty calm (most of the time, there is the occasional siren). For travellers its so easy to get from the Heathrow Express at Paddington and safely home in 5 minutes.
Westbourne Terrace is conveniently located for Hammersmith & City, District and Circle line tubes, Heathrow Express and National Rail from Paddington offering easy access in and out of London.
