Angela's place is pretty near King's Cross, but if you are coming with luggage, do note the walk to the place is a little upslope. The buses might also skip some stops which leaves you walking quite a bit more than expected. But this is due to road works, which seems to be very common in London during this trip of ours.
The house and toilet were extremely clean and the hot water was great (perfect for winter). Heating was also awesome. It can get a little stuffy at times, but you can just open the window to ventilate the room.
Do note that you cannot store your bags after or before check in/ out but Angela gave a great option to a baggage storage place (it's written on the bedroom door). We used the link and paid 5 pounds per big bag, but if you go down to the store itself, it's only 4 pounds :)
There is a Waitrose at the halfway mark between King's Cross and Angela's place that is pretty well stocked if you decide to eat in. We had a lovely experience staying with Angela and would love to come back again in the future.
