First, a note about Jake: he is a very hospitable host and went above and beyond to make our stay a wonderful experience. My sense is that he knows exactly how much space to give you. In other words, if you don't want to interact much, he would leave you to yourself. But for people like us who wanted some conversation and to spend a little time with the host, he makes himself available. We really enjoyed being able to just sit in the living room with him and watch the tube and talk a bit about our day.
Next, a note about the flat: location, location, location. Jake's flat is in an ideal location for those wishing to see the sights of London. A short walk from the Underground and even shorter walk to bus stops, buy an Oyster card and you will have the whole city at your fingertips from Jake's apartment.
The flat is clean and tidy and had everything we needed and is in a beautiful old building. The bedding was comfortable. The shower has great water pressure and the water is hot. We didn't use the kitchen too much but it appeared to have everything you could need for food preparation.
