My stay at Sally's was nothing less than perfect. I arrived in the evening and Sally gave precise instructions on how to arrive at her place, as well as perfect check-in instructions. The place was clean, simple (I love simple), the bathroom super clean and warm (which is one of the most important aspects for me when staying at an airbnb).
I learned very fast that the easiest way to get connected to the other underground lines is to change at Bank - so even though when I arrived I felt it was a bit further than my usual airbnb choices (as I was coming from LHR), once I learned this then getting anywhere else was just a hop away.
Sally's place is also very close to a lot of fun eateries. The place has a lot of lively crowd, especially in the evenings - so if you are feeling for some company do not feel shy to grab a drink and strike a conversation with one of the locals. In the mornings, if you feel like doing something relaxing then it is just a one-minute walk to an open market with a lot of knick knacks to check out.
All in all - I would give Sally's place all the stars it deserves!
