I was spending a week in the house in Skinopi. I used the house as a remote workplace (having virtual meetings and hosting workshops) and when not working I was roaming the island for beaches. It worked perfectly for me! With regard to work, the wifi was adequate and reliable. The team in Adamas was very helpful and responded promptly to all of my questions. Thanks guys! I also need to mention my contact at Nikos Motos (who rented me a quad bike), he was the kindest man and extremely helpful too.
Apart from that the place is just wonderful. If you are looking for a small, isolated and beautiful spot; look no further! This is highly recommended - and I'm sure I will be back.
