We spent about a week at Nektarios place and had a great time! We had a warm welcome by a friend of Nektarios.
The place is bigger than expected and we (two persons) had lots of space. We enjoyed cooking in the well equipped kitchen and both terraces are great to spend time in the morning and the evening.
Even though Agalianos itself is quite small, you will find a Minimarket at Kerames nearby. Also, the beaches nearby (e.g. Trio Petra or Plakias) are worth visiting. Please note: The weather in this part of Crete can be a little tricky sometimes. After 2-3 days of consistently strong wind (which makes it a little uncomfortable at the beach as the sand is being shot at you) it will be back to normal. So don't worry or go to Rethymno for a daytrip. :)
