My wife, my sister and I spent three nights at Giannis' apt. Giannis is a very responsible and helpful host. He contacted us days before our arrival and met us at the port to drive us to the apartment. He was also so kind to print our boarding passes for the return flight and bring them to us!
The apartment is located on a hill about 12-15 minutes walk from the old city (Kastro). It is located in a very quiet neighborhood (no noise at night) inhabited almost exclusively by Greeks. This is a big plus if you consider that the spectacular historical center is also very noisy and chaotic. There are also several parking lots close to the apartment (we rented a car for two days, and always found a parking spot nearby). Let me add that from the apt location is easy to drive to the most spectacular beach on the island Plaka (I would definitely rank it among the top 5 in Greece), Demetra's Temple and the picturesque villages in the island center. Another plus of the apt is the balcony where the three of us had aperitifs and one full dinner. From the balcony one has the far view of the sea.
The apt is very well equipped for cooking, washing, ironing, etc. There are two monitors to watch TV, a larger one in the living room and a smaller one in the larger bedroom.
The smaller bedroom has anyway a full-size bed, but going around it is a bit difficult as space is limited. Moreover, there are no closets there.
