Blue-Downs View is just 5 minutes walk from the seafront and even closer to Ventnor shops and restaurants. The accommodation is clean and comfortable. There is also a small patio garden with BBQ, though we didn't use it because we ate out on walks around the south of the Island. I'd also recommend the Spyglass pub down by the waterfront, which we frequented after walks.
One word of caution is that there is limited stay parking at the front of the house. There is a garage nearby the property which was fine for us as we walked mostly from Ventnor but might be less convenient for those who plan to use the car a lot.
