We had a great trip to London staying in David's well equipped and very conveniently located apartment. Everything was easy - from arrival to having a good range of supplies when we first arrived.
There are some great spots for breakfast and other meals within 5 mins walk, plus at least a couple of supermarkets within the same distance.
The street noise can be significant at night, but this is London and it is King's Cross - you don't come here looking for a tranquil retreat.
Also, a little tip for the lift (we found out the hard way) - it says inside the lift that it can take 5 people. It can't. Three people is the maximum as per the advice from the front desk!
Thanks for a great stay. We would certainly stay here again.
