Just a one day stay , hotel is on the beach road lots of beach space , the centre of Vasto is 2 to 3 km away uphill, we drove but there will be public transport , very few gift shops near the hotel.
Get a room with a balcony , we had a table for snacks and drinks, the balconies on the first floor are enormous but only two of them , could have done with sun loungers , we ate out in the evening , but the breakfast was fine . No swimming pool so you have to like the beach.
