So unfortunately my visit was slightly marred by some other 'guests', which I have to mention, but hopefully they won't be a problem for any future visitors. I stayed for 5 nights recently, arrived on the Sunday pretty late, crashed out, up early Monday and out to work. When I got home that evening the bedside table in my room was crawling with ants, I can count 15 in one picture I took, which is a lot on an area that size (had a bad experience with a previous trip where the host denied all the problems we'd had, so I always take lots of pics of any issues!). I texted Nev and he asked if I'd left food out, which I hadn't. I asked if I could move rooms and he said I could take the one next door, just for the night, and the cleaner would come next day. Unfortunately the room next door (and its en suite) were also entertaining quite a few ants, so I used my own room anyway. Cleaner came in the morning but unfortunately, when I got home from work the situation was the same, and I also found ants in the downstairs bathroom at that point. So this was Tuesday night, at that point Nev told me he couldn't get an exterminator 'til Saturday, so all he could offer me was a refund for my remaining nights, if I wanted to leave. Trouble is that a room in central-ish London, that close to xmas, with no notice is so expensive that I literally couldn't take that option, so I just had to put up with the ants. Their numbers did dwindle and there were only a few wandering around by the end of my stay. I do feel like that situation wasn't particularly well handled and that it would have been possible to get an exterminator in less than 4 days or that I should have been offered a discount/part refund.
However, if we forget that, and assume the ants have been dealt with, then I was say that for most people this would be a great place to stay. The fixtures, fittings and decor are all of a decent standard and it's obviously well looked after. Location is fine, although lots of tramps around and the area is a little bit rough, but not terribly so and if you walk at a very brisk pace you can get to Manor House tube station in 12 minutes (careful if you're coming for work though, it gets hideously busy in the morning!). The room I was in faced out onto the main road, which is a very busy bus route, essentially 24hrs a day, so if you're a light sleeper I'd try and book one of the other rooms in the house.
You can't really tell from the pics, but this is nothing like your usual AirBnB, so much so that I was puzzled as to why it was listed on there when I arrived and saw it properly. It's not a home, with a family living there, as you would normally expect, it's much more like a B&B, or even a small hotel. That's not necessarily a negative btw, it's just that if you like AirBnB for that vibe of visiting someone else's home then this place probably isn't for you.
So in summary, and assuming the ants are gone, I'd say it'd be a great place to stay for most people. Don't get this particular room if you're very sensitive to noise, and just be aware that the house is pretty much a small hotel, and not at all a family home.
