We had a great time staying at Mariam's and Stelios place. The house was very clean and spacious and had everything that anyone could ask for. The position was very convenient with supermarkets, pharmacy, bakery and other stores at a walking distance. It is just above the beach, ideal for long walks. Only 5 minutes from the White Tower and 15 minutes from the central square. Mariam responded quickly to the communications we had and was willing to answer all of our questions.
I would definitely recommend this place for a nice stay at Thessaloniki!
