The accommodation could not have been better, and the pictures shown are true to life. The location on the site was great, a short walk to the Haven activities centre and to the beach, but in a quiet area of the site (no screaming children playing football etc).
Seton Sands is a convenient location for exploring Edinburgh and the surrounding area with really good public transport directly from the site (an hour into Edinburgh at £10.50 for a family day ticket).
