We've just finished our 10 day stay at Casa Bianca in the bottom (orange) apartment. The apartment is a decent size for a couple, with dishwasher, full fridge freezer and oven in the well equipped kitchen. The other apartments are bigger but are equally well equipped. The pool area is shared between the 3 apartments as well as the bbq area and we enjoyed making friends with our neighbours.
The setting is lovely; great views down over Gaios and about a 10 min walk down. We always drove or got a taxi back up as its very steep and I'm 7 months pregnant but it's doable for those who are reasonably healthy. Gaios town has plenty of bars and restaurants for the evening, plus it's easy to jump on the boat to Antipaxos in the morning. We hired a car (beware the roads are not wide and not always well maintained- not one for the nervous driver) so had fun visiting Lakka, Loggos and various beaches.
The owners of the villa are lovely, friendly and helpful. I would recommend this place for those looking for a peaceful holiday with easy access to the town, plus a nice view and pool. We would definitely go back but maybe not when we have very young kids as it may be a little too quiet for them - we'll see! We'd definitely like to return in future.
