I'm so sorry to hear you were cold. If you had told me I would have brought you another heater. I will now fix one permanently in the bathroom and the kitchen - no other guest had mentioned it till Belle last week and now you. It was very cold weather, unusually cold, so I obviously have to be ready for that.
Regarding transport, unfortunately there was a bus strike one day and the tube station closure the other, when you were here, explaining the slow journeys. This is very unusual and I confirm that the journey to central London is usually around 30 minutes, even in rush hour.
