The house of Argiro and her mother Irini is very has a very nice and special atmosphere. Due to the thick walls you hardly need the air-condition, which works very well anyway. I was there in the last days of August which was medium to quite hot.
Topolia is a lovely little village, that in my opinion deserves exploring. Most people are very friendly and helpful. You can also hike in the Topolia gorge, which runs right next to the village.
Elafonisi beach and Paleochora are easy to reach by car. From Paleochora at the south coast you can take the ship to beautiful locations, which you can't reach by car. We went to Agia Roumeli and walked up the Samaria gorge. Loutro is also very beautiful and has no cars.
By the way: You really need a car unless you plan to stay in Topolia during your stay.
In the village there is a bakery and a Mini-Market, which provides essentials, For more groceries we went to Kissamos (Kastelli), which has several large SYN.KA supermarkets, that are well stocked.
Topolia has very good restaurants and Kafenios (Greek cafes).
The house itself is generously stocked with tasty olive oil, vinegar, Raki, coffee, sugar and more. The owners make their own products!
I personally was also quite fond of the hammock for reading books or just relaxing. The two terraces are a great plus for enjoying meals etc.
I can definitely recommend the Mulberry Villa and if I come back to Crete I would definitely chose it again.
