We stayed at Steamer Quay for four nights at the end of August.  The site is compact and well laid out  without feeling in any way cramped and is located across the road from Dartmouth ferry office with lovely walks along the river in both directions.  Do walk in the Dartington direction and visit the steam railway and wildlife centre - lovely cafe opposite the railway station.  Totnes is on your doorstep - interesting shops and plenty of places to eat and drink many of which are dog friendly. River trip to Dartmouth is recommended but check times as they vary according to the tides. Lack of electric hook-up didn't bother us at all (probably adds to its peaceful feel) and the toilet block, whilst dated, is spotless and functional - the hairdrier was much appreciated.
