Stefania' flat was conveniently located next to the Gloucester tube station, and is within walking distance to the museum district, Imperial College, and Hyde park. In term of the flat itself, it was a great experience to stay, though a few things could be improved. Upon checking in, we found there were a thin layer of dust on everything that we had to wipe it out ourselves. The wifi initially had very low speed initially, but Stefania was kind enough to diligently resolve the issue by calling the ISP. Also be aware that the water heater had rather small capacity so it may not be enough to serve a group of 4.
