Sebastian is a great host, making himself available for any issue and timely in all respects. the flat is in an area with a lot of mid-sized hotels and very close to Earl's court station (right off the Picadilly line that connects right to LHR) so convenience is very high. The internet is super fast (yay!) and the small kitchen worked fine for me. There is also access to a washer and dryer.

My only area of improvement would be the bed and bedding -- you have to like a bed on the "harder" side -- i'm personally not one of those people so I didn't find sleeping so comfortable and there is definitely room to up scale the linens and bedding.
