Joanna's is a comfortable apartment in a great location, only an 8 minute walk from Borough underground station and also within 15 minutes by foot from e.g. London Bridge, the Old Vic and other places. Good bus connections too. Despite a big main road nearby, the place is really quiet also. Joanna is a very responsive and friendly host who always got back quickly on the couple of extra inquiries we had.
And for those who'd enjoy it, one should mention the neighborhood pub, The Ship, only a few minutes away and with a beer garden -- perfect for a relaxing drink on a summer's evening!
