My mum and I stayed at Agee and Smith's place for a long weekend and we couldn't have asked for a better place to stay. Agee and Smith were friendly, extremely welcoming and so accommodating making sure we had everything we needed, they even lent us a fan - which was just heaven during the heatwave! As the guest house is separate, we had our own key and were able to wander in and out at our convenience which was very helpful.
The house is in a fantastic spot in the gorgeous Chiswick and conveniently located just down the road to Chiswick Park station. There were a couple of problems during our stay on the District line for Chiswick but you can just as easily use the Piccadilly line to Turnham Green which is just halfway up Chiswick High Street. There is some noise due to the trains but this didn't affect us and my mum is a light sleeper, so unless you're planning on staying in all day it isn't a problem!
Overall we loved staying here and would come back anytime - Thanks Agee and Smith! :)
