Overall we enjoyed our stay in London. The location of Sarah's place is nice. It's a bit of a walk to the tube, but it's a couple blocks off the London Bridge which was fun.
We were disappointed that we overlooked the no air conditioning aspect (which I guess is pretty common in London). We also had trouble with the wifi not working which was a bummer as my husband had to do some work while there. We had to restart the router multiple times after initially having to call the help number provided because it wasn't working at all. It also took Sarah two days to message us back on airbnb about the wifi password (we were only there for 4).
As my husband put it, you can tell this place has been rented out for a while. Under the bathroom sink there's some definite wear and tear. There was a fan left for your use, which was nice, but the fan itself looks like it's been used for decades and never been cleaned. The apartment is located in a co habited work and living space which was fine but a little odd.
I'm leaving this review to help give future renters a more clear and comprehensive idea of what to expect at Sarah's place, not to deter renters completely.
