I cannot imagine that there is a better place to be based to explore and enjoy Paros. Don't hesitate to book it.
Firstly, the apartment (and the other two adjacent to it) has undoubtedly the best views on the island, no question about it - just look at the pictures. It is almost surreal to start your day enjoying the view, a coffee and breakfast on the terrace over looking Parikia town and even more so having a "sundowner" in the evening while watching the world famous Cycladic sunset. The units are well appointed, spacious and comfortable.
Our/your hosts, David and Erika are down to earth, knowledgable and giving. When we arrived they gave us a thorough introduction to the apartment and points of interest, places to eat, and things to do in Parikia and Paros. A selection of "goodies" was in the fridge meaning we could have our first lunch without going shopping. They have lived on Paros for 25 years and have a wealth of local knowledge that really made our visit quite special.
You do need a car (or at least a powerful motorbike!) to stay here; but you probably need one to get around Paros anyway. The apartment is only 5 minutes from anywhere around Parikia and no more than 15-20 minutes from the other "major" villages on the island - Lefkes, Noussa, Piso Livadi, Alyki etc.
My advice is to double the amount of time you plan to stay here and book today!
