We had a great stay at Dimitris’ place. Very clean, stylish and well-equipped apartment. Amazing terrace with panoramic view and comfortable patio furniture. Dimitris was a very attentive host, and answered messages almost immediately whenever we had questions. The apartment feels safe with quality security doors, and the building itself is locked at night. The neighborhood is calm, although there is some traffic noise when on the terrace from a larger street about 100 meters away. For close dining, there is only a 6 to 8 minute walk to some great cafes and restaurants in the heart of the Koukaki area - great for travelers who like to go where the Greeks go - not packed full of tourists!
Using the metro is not so convenient, as you have to either walk 13-15 minutes or take a bus to get to the station. However, a taxi to Syntagma (for example) from the apartment is only 3.50€, so 2 or more people together might actually Save money taking the taxi, and a short walk to a busier street is all you need to hail one as it drives by.
An excellent place to stay, central yet away from the tourism. Great value for the money. Highly recommended!
