The villa has everything you need. It has an amazing view of the sea, a swimming pool, a roof terrace, a balcony, fully equipped kitchen, etc. We relaxed as soon as we arrived, as the only thing we had to worry about was where to go!
The people are very friendly in Crete and we saw many amazing places, ate gorgeous food, drank delicious wine (recommend the wine tour nearby) and enjoyed exploring in general. A car is definitely needed to explore.
Plaka itself is lovely. We usually went there in the evenings for food and drinks - thoroughly recommend having the kleftiko at Christina's and also having drinks at Taki's Bar.
Would definitely go back - the villa is perfect for families or groups of friends. I'd like to go back in the summer and sleep on the roof terrace :-)
