I stayed at Duchy House for 5 nights and had a great time. Location doesn't get much better than this (lots ot great places in walking distance and plenty of bus, tube and rail options nearby), clean, lovely reception (even though I arrived very late) and the option to leave your bag on the day of departure is very convenient . Yes, it's on a busy road and may be too loud for some people, so perhaps not the best option if you're a light sleeper, but I slept just fine. Would definitely go back and recommend this place.
