I can only agree with what other reviewers have already said - the house is fabulous! Beautiful terrace, where we spent a lot of time. It was quite windy for the first 3 days but the terrace is quite sheltered so it felt more like a breeze. Without this, it can get rather hot.
We decided to eat out at the local tavernas (and yes, Dionyssos was also our favourite - on top of the usual menu, they also offer specials, which is a range of dishes presented by the chef, all of which are very generous portions), rather than spend time cooking - although the kitchen seemed perfectly adequate for preparing meals.
Also as others have said, watch out for headspace unless you are a fairly short person.
The bathroom may be small but the shower is lovely and the floor dries super quickly.
The beds are super comfortable and there's a selection of fans if it gets hot in the night.
Loo roll, handsoap and washing up liquid (and dish cloths are also provided), we bought replacements but didn't actually need them. No other condiments like salt, pepper or cooking oil.
Myrthios and Plakias are quite remote so to see other places you would have to spend a fair amount of time driving/in the car - we decided not to do this and stay local most of the time. There are lovely local beaches and Plakias has plenty of shops and tavernas. We did spend half a day in Rethimno, the market wasn't anything special but the old town was lovely and great for a spot of shopping.
In summary, it's a fantastic place to enjoy the sunshine from, we had a wonderful time and did not want to leave.
