We spent the months of Feb and March in Villa Morpheus. We didn't meet the owner but interacted with his father, who was very helpful if we required anything but otherwise didn't interfere and left us alone.
Agia Pelagia was fairly quiet at that time with most shops and restaurants closed. We did find a couple of friendly tavernas but generally cooked in the villa or went to Heraklion to eat.
While within ten minutes walk from the village the shortest route is very steep and wouldn't suit the elderly or infirm. A car is also fairly necessary in the winter as there is no regular bus service until the season starts.
The villa itself is a lovely size and very homely with plenty of kitchen equipment, comfortable seating, and a nice spacious main bedroom. There is also an open fire and air conditioning/heating, which unfortunately we really needed as we experienced what we were told by locals was the 'coldest winter on Crete for thirty years'.
The most positive aspects of our trip were the price, the space and cooking/dining facilities in the villa, and the view. On the downside while the house must be lovely in the summer, it is difficult to keep it warm in the cold weather; the hike up the hill was a bit severe for us (not in the full bloom of youth); a lot of dogs in the area can erupt in howling sessions at any time of night or day.
While we had a good overall experience and bring away a lot of good memories of our time in Villa Morpheus we honestly couldn't recommend it for a winter stay.
