Great location, very clean, communication with the staff was excellent. I visited in late December and there is only a space heater for the entire flat but it works surprisingly well in heating up the whole place. I stayed in Flat A which is on the first floor. It's on a busy street of restaurants but it was pretty quiet regardless, I think in the summer when the windows are open, noise could potentially be an issue but at this time of year it was no problem. Also, by 11pm everything was closed so it was no problem with sleeping night. Short walk to all the great spots, right off Bond Street tube, and not far from Baker Street tube also.
