Wonderful flat in an area untouched by mass tourism but still very near to central London with easy access by bus or on foot. Nearest tube is Kennington, app 10 minutes walk away. The flat is recently renovated and very bright, clean, comfortable and surprisingly quiet. The bedroom faces the small, enclosed garden and so is both private and quiet.
I was completely undisturbed by traffic noise, as there isn't much through-traffic in the street. Santa is a fantastic host, very kind and welcoming; you'll be in the very best hands. From the flat it takes about 40 minutes to walk to Lambeth Palace or Westminster, and in nearby Doddington Grove is a Santander cycle station (where 2 pounds will give you free access to city bicycles all over London, which I used widely). I don't need to look for another place for my next visit to London; I'll definitely choose Santa's flat again next time.
