I loved staying at Sophie's flat in London! It is shabby chic and comfy. Two bedrooms and two baths would make it very easy to accomdate up to three or four. I stayed alone and enjoyed the amount of space. There are two lovely comfortable decks, one towards the busy life in London and one secluded and private off both bedrooms.
Coffee houses, organic grocerys and yummy neighborhood bistros. Don't miss Hill & Schronk (butcher by day and dinner house by night)!
All in all, I'd surely chose Sophie's flat again!
