My three friends and I travelled to Crete for a brief holiday, and we really enjoyed our stay in Marios' house. The house itself is beautiful--the pictures are accurate. There's plenty of space to live comfortably. The bathrooms are nice, and the beds are comfy. We enjoyed using the kitchen to cook dinner, and there's a few supermarkets nearby to purchase food from. If you want to watch TV at night, I would recommend bringing a laptop with a USB port to connect to the TV via the HDMI cable to watch videos with a streaming platform.
Marios is an incredibly kind and generous host. When the water shut off in the house, he came to the house to fix it and offered to take us to a beach on the southern side of the island (Matala). This day was a great experience. It was fun and insightful to travel around Crete with a local--he told us about some history and pointed out important landmarks.
The area of Agia Pelagia is quiet--if you're looking for bars at night, this is not the place. However, there are great local restaurants right on the beach, just a short walk from the house. The beaches in the area are calm, and the water is beautiful clear blue. I'd recommend getting up early one day to watch a sunrise!
In all, my stay at Marios' house was great, and I'd highly suggest staying here.
