My friend and I spent the New Year period in this flat and very much enjoyed our experience. We especially appreciated Allan and his assistant Susie going out of their way to provide an early check-in for us. The flat is a perfect place to stay for a relaxing and enjoyable time in London. You are right next to the underground with good connections to all of Central London. The area surrounding the flat is also very diverse and worth wandering around if you have the time and inclination.
All amenities were in full working order, though the Wi-Fi could be patchy in the conservatory area - make sure you have plenty of data allowance on your phone just in case.
Overall, we greatly enjoyed our time in the flat and would stay here again should the opportunity arise.
