Pros: Caitlin was extremely sweet and welcoming, the flat is very spacious, the showers are phenomenal, Battersea is great, and the weather was lovely.
Cons: The spot is not super close to transportation to get to city center - 30 min ride on busses that were hit or miss on reliability. The place also certainly has a mildewy scent to it, as is the fear with basement apartments, definitely wasn't great for my allergies.
All in all, a good value spot, but some things that could use improvement. Caitlin is a great host though and I could very much see her resolving the issues above in the near future!
