We (my wife + me) stayed with our 3 years old son at Marianna & Stavros House A. We had a wonderful time in their house.
The house is located very close to a great beach (5-10 minute walk), which is perfect for small kids. At the beach you will find some nice restaurants and small beach cafes, where you can get some snacks. You can drive with a taxi to the beautiful Naoussa (the next city) within 10 minutes.
Marianna & Stavros were very friendly and enormously helpful. We traveled a lot via airbnb and met a lot of host, but these two were exceptional.
To sum it up: If you visit Paros with kids, this house will be a great choice for you!
