My husband, 7 month old son and I stayed at Petra House for 3 months so we know the property well. Polina is kind and helpful and very quick to reply via AirBnB with any questions. She actually lives in Athens and runs a busy company so you are unlikely to meet her at the house in Kea - we only did once in 3 months. On the other hand her parents largely spend the summer in Kea - they also live in Athens but have a small cottage 30metres away on the same property so you share a laundry, washing line and grounds with them. Mary and Vassilius are very lovely, kind people and were wonderful with our young baby especially. Vassilius keeps the pool spotlessly clean and Mary kept us stocked up with bags of local spinach from their garden. With them always around it is useful if you have any problems with the house however this arrangement may not suit everyone so it’s worth being aware of. The house is simple but tastefully decorated and has everything you might need in terms of kitchen appliances etc. It is the lower level of another house advertised on AirBnB as Villa Thea and shares the swimming pool although it has a separate outdoor dining area at the back so you have your own space. It is in a great location - not too far from the port, supermarkets etc and near some of the best tavernas and bars but far away to feel private and peaceful. It is up a steep hill with a lovely outlook over both Voukari and Otzias and a great view of the sunset. Kea itself is wonderful - there are a lot of Athenians with holiday homes there but hardly any tourists which for us was a very good thing. It is quite affluent so the prices are not as low as on some islands but not as high as Mykonos or Santorini. There are some great beaches to explore and well marked hiking trails. The island is well suited to those with a sense of adventure as some of the best beaches are 1/2 hr - 1 hr drive away and the roads are very steep and windy and often unpaved. You definitely need your own car, ideally a 4WD. Although we didn’t use it as we brought a rental over from Athens, Polina and her parents can provide a good 4WD car at a very reasonable price. One challenge we faced was when guests arrive to stay upstairs in Villa Thea who were surprised to find us downstairs - perhaps this should be advertised more clearly? We always got along very happily with the guests upstairs we just felt awkward that they hadn’t been expecting to share the pool with another family. Our only other issue was with the wifi. One of the things that was very important to us in choosing a house was that the wifi was fast and reliable...
