Was a bit hesitant before writing this, but - sorry - didn't have a good experience.
I need to admit that my disappointed is more because of false expectations than of what the place is.
Going back to the details most of what's described there is more or less accurate.
The room IS cosy - what you see on the picture is not a sample of the room. It IS the room. When packing before flying back home I didn't have room to stand when having my stuff on the floor.
Also, the furniture in the picture are not a sample. That's everything. Not even a closet.
The room is indeed clean, no comment about that. Once you get out of the apartment though, it's very much the opposite. Smells of garbage like I ran into in some of the not so nice parts of Delhi.
Should I mention that it's not 4 minutes from King's cross but more like twice as much? That's minor, although when in a big rush with all my lagage it was a bit frustrating.
The shower/restrooms are indeed clean but the shower head keeps falling (both height and angle) so I needed to hold it when taking a shower. One more thing about the shower, it indeed is a shared one. Between four different rooms. Almost never got to get there on a first attempt.
I realized only being there that air conditioning and/or fans are not as common as I'd expect (or rather want) in the UK and with the hot days I had there the room was boiling hot, the window faces the sun directly which doesn't help, could bearly sleep.
To be fair I was offline most of the time (something with my phone) so I need to say that the owner didn't have a chance to say anything about the shower, but I'm not sure the other things could be fixed during my two nights there.
All in all, again, I might need to blame myself for not going through and asking about every single detail, but somehow I expected either for a bit more "generosity" (for lack of a better term) rather than the most minimalist version that you could imagine that would fit the description, or some of the details to be there, or at least for the price to better reflect the situation. The way things were, I tried spending as little time in the room as I could. I know that London is expensive, but if I'd pay more than 100$ per night, and just thinking of a previous time I got a whole nice apartment in a much MUCH nicer neighborhood in Rome, few minutes walk from the Vatican, with many other things I didn't expect and where just there rather than the bear minimum for an amazing price, that takes out the fun of AirBnb, that to me means people opening their house in (at least a tiny bit of) a generous way, and not just a business (although it obviously is), just a way to make money. I'd look for something else next time, sorry.
