Easy check-in and check-out. Kostas was a good host and asked if everthing was alright when we arrived there. He answered fast after having a problem with the heater (still after solving the issue it took a long time to heat up the place and still it was cold!).
We stayed with 6 people for 3 nights. If you are planning to stay longer with 6 people there we wouldn't suggest it (only one bathroom and not 1.5, some mirrors in the bedrooms would be also nice ;)).
But the communication with Kosta was easy going and fast, as well as the price and getting easily by bus and even by foot (30minutes walk) to the center.
