Hannah is great! She was very good at communicating check-in, how to get to flat, etc.
Hannah's flat was great for a week long trip in London. The area is very quiet (though you may wake up to kids playing outside as the flat is across from a school), and is a nice retreat after a day spent near the busier parts of London across the Thames.
Sever bus stops close by and the train station is about a 10 min walk. Plenty of good cafes within walking distance, as well fantastic food to be found down by Elephant & Castle. Overall, a great place to stay if you want to have fun in London!
