My sister and I had such a wonderful time at Maria's house and in Sivas, which was the perfect home-base to explore the South of Crete around Matala with our car. (We were very happy to stay in cute Sivas and not in the quite tourist-y Matala!)
Maria's house is a wonderfully restored, traditional Cretan residence. You see in the many little details how much care is put into the house and our stay there, with a welcoming basket that had the best olive oil we tasted on our entire vacation (her family produces this limited edition organic olive oil that they now give away as presents to friends & family, not yielding enough to sell--we asked ;-) ).
The bed was comfy, the kitchen was well equipped, everything was in order and new. When one of the garden chairs' fabric tore, Maria replaced it the same afternoon and generally communication with her was very easy. Check-in was a breeze (lockbox). Really, I can only say good things about her house and highly recommend it to anyone!!
