We had a fantastic three-night stay at Jac and Tim's flat. The flat itself is great for families or groups of friends; it was great to have the kitchen (though we didn't cook much of anything, the equipment all looked great, and we did make use of the fridge and teakettle). It's in a good location, around a ten-minute walk from Kings Cross/St Pancras (trains from Gatwick) and even shorter to Russell Square station (Piccadilly line from Heathrow). Tim met us at the flat and gave us a tour and keys; they were very responsive via Airbnb and were really fantastic hosts. I'd absolutely stay here again!
