It's actually a 2-bedroom villa. The 3rd sleeping place is not a bedroom, rather a cave like room where kids might enjoy, bit was too small space and rather claustrophobic (it's in the basement as well).
We never met Konstantinos, as he never showed up. Thanos (who was introduced as host) took care of all the formalities and was very good.
Amenities - Aside from the bedroom, the pool is actually a good sized Jacuzzi-style tub - it's good for 3 people to sit, but one cannot swim.
The barbecue has no grates, so unusable
Accessibility - The villa is a good 10-minute solid uphill walk thru' narrow cobblestoned twisting paths. Even though Thanos helped us carry our bags during check-in, it can be a significant factor if you have some luggage (we visited from North America for a week with minimal luggage).
