I stayed at Polly's place for a week and had a great time. The location is fantastic - very close to frequent trains and buses, as well as to supermarkets and other community amenities. The unit itself was very comfortable, with a well-equipped kitchen and space to relax inside and outside in the back garden. Polly was very responsive as a host and made the check-in process seamless.
One thing future visitors should be aware of is that the room I stayed in faces east and catches the full morning sun - this can make the room quite hot in summer, especially as there is only a fan in the room (but it is a nice and strong fan!).
