That was awesome place for long term stay. We spent here 2 months and I want to say thank you Debbie for your responsibility and responsiveness! Spacious apartment, fast wi-fi connection, netflix, cooking facilities, big balcony, supermarket in 3 min walk, closeness to metro station (8-10 min) and city center (20-30 min).
Despite that, I have some suggestions for the upcoming visitors:
1) During the winter season, even with the air conditioner heating, the apartments might be a bit chilly. Therefore, it is advisable to bring some warm clothing if you plan to stay here.
2) I would not recommend to walk around the area after dusk. Although everything was fine on the way to Omonia metro station, I felt unsafe while walking towards Attica metro.
