Jason’s place was just what I hoped it would be. Our room was very private with an en-suite bathroom that provided us with everything we needed. It is in a great, central location —Kings Cross station is directly across the street— and that made traveling to different parts of the city easy and stress free. There are delicious restaurants in the area (our favorite was Dishoom, right up the street) and fun places to go for drinks after.
The only thing I wish I knew was how high-traffic/high-volume the area surrounding the flat is. It can be very loud with cars, sirens, and (at times) random music playing right outside the window at night. Bring earplugs!
