Our stay with Konstantinos was not the best. A few things were not his fault (for example, because of a glitch in the AirBnB system, our listing said the hot tub would be available to us, but it was not supposed to be listed until April 1st. Konstantinos kindly refunded half our payment and got the tub up and running by our last night) and he did try to remedy them. That said, our check-in was rather fraught (he wanted us to get their by private transport and seemed annoyed to have to give us directions when we said we were coming by bus), he gave us a limited time to arrive (we had to be there by 7:30 to check in with him, which wasn't possible because of our flight and bus schedule), and then eventually sent a couple pictures of the road to the place and put the key out for us. Then there was the hot tub fiasco, which he did work quickly to resolve. Most problematically, however, were the two times that women with keys to the place walked in on us. Both happened mid-morning. One, apparently, was someone planning to stay there? The other was the cleaning crew arriving an hour before our check-out. If I was traveling alone, this would have really bothered me a lot. There's no safety latch on the door to prevent that from happening.
The place itself was cute and well-kept. The shower does get the entire bathroom wet, so don't keep your clothes in there! It's a little off the beaten path and in a more residential area, so you can hear kids playing/babies crying from the surrounding homes, but that wasn't a big deal. There was a really friendly black cat who kept trying to get into the house and loved attention.
Overall, the place was just okay and a good price, but our experience was less than stellar.
