We stayed at Nissa's apartment for a month, while we were looking for a more permanent place. We never really met Nissa because she was traveling, but she was very nice and responsive over email (even though she was a bunch of time zones away!). I definitely liked the apartment. It has character and personality, and the location is convenient (well connected). Plus, it was relatively cheap (always measuring by London's crazy standards), given the location and size. Like someone wrote in a review, this place is a bit unconventional and might not be suitable for everyone. You saw the picture with the bathtub next to the kitchen, and the outdoor shower. Don't rent the place and then complain it was unconventional :-)

A controversial point in the reviews is the cleanliness of the place. The floors, counters, tables etc were definitely clean when we arrived. But it is also true that there is some dust in the shelves and in the basement (which you'd normally not use, but we had to enter to access the fuse box) simply because there's too much stuff in/on them. The same decoration and stuff that make the place charming also make it difficult to keep it super-shiny. The same thing applies to the outdoor shower / bathroom. It definitely has personality, but you simply cannot expect a shiny tile floor in there. In absolute terms, the 4-star average rating in cleanliness seems fair to me.

Another controversial point seems to be the Internet connection. The wifi is indeed spotty, even by the window. Some of our devices connected more or less OK, and others couldn't connect at all. Overall, I'd say it's fine for browsing / email, but not for serious remote desktop or similar applications.

Finally, I would like to comment on a few smaller issues, which might be minor or negligible for some people, but bigger concerns for others:
- It is pretty cluttered with stuff. If you're there for a few days, you wouldn't mind at all. But if you're staying there for longer (like us), you might miss some free drawers / shelves for your stuff.
- This is very personal, but I found the mattress (even the harder one) too soft, even if it's directly on the floor. Again, I probably wouldn't mind at all for a few days, but it's something you might want to consider if you're staying for longer than a week.
- The general condition of the apartment is old (again, like you could see in the pictures!). There were some minor problems with water leakages and appliances while we were there, but nothing super-serious.
