I stayed at their place for 2 weeks. My stay was nice but not perfect. Usually at the end of a stay, it is customary for the host to tell his guest that he wish for his return. On my last conversation with Alastair and Sera, it did not happen; and I suppose, this idea did not come to their mind.
Fourteen days earlier, It started very well. Alastair took my suitcase up the stairs. He is a very nice, serene and kind person. I do not see him holding negative thoughts against anybody.
As hosts Alastair and Sera covered all the bases. Every accommodations in the house was in working order. Everything basic, simple and nothing fancy.  Here and there you could find traces of the work left by jack-of-all-trade that fixed the house thinking with the lowest expenditure in mind. Not that I care very much. The price they charge is very reasonable.
The bedroom picture on Airbnb is truth to reality. But there is no table there are no chairs.  Basically there is one big room in the apartment that serves three functions: kitchen, dining room and living room with a sofa and TV.
The last evening I was there when I handed my keys to the apartment; I mentioned that I found the bathtub slippery because the bottom of the tub is curved laterally and when you take a shower someone like myself needed to be careful not to slip. (They said they did not have that problem.)  On the same token Sera mentioned my entrance in the kitchen room when the door was closed two-day-before was not appropriate because when the door is close it means « not to be disturbed ». If I remember correctly I went in, knocking on the door to get copy of the newspaper I had left in the kitchen table not realizing the closed-door-no-entrance-code also applied to the kitchen. (…)
The immediate surrounding from the house leading to the Tuffnell Park station ( 9 min walk according to Google Map) has very little appeal to me except for a nice small cafe called the Literary Cafe with good Wi-Fi and coffee. On the other side, the Kentish Town station ( about 11 min walk) has more to offer with a good supermarket, banking machines some OK restaurants and a post office. I did not use the front door bus stop because I found it not convenient to where I was going or how much time it took me to get there.
London is my favorite city. I am looking forward to get back to London. Maybe next time I will not look for a superhost; maybe a regular host will do.
