I stayed in Bills and Helena's apartment for two months on a business trip and it was perfect. Helena was always quick in communication and made sure that I had everything I needed. I was living alone and felt very safe in the area, I was never afraid to walk outside at night. There's different grocery stores and multitude of amazing restaurants nearby, as well as a bus, tram and metro station. The acropolis and the city center is just a short walk or metro ride away. The apartment has everything I needed and it was very nice to stay in even for a longer time. If you're looking for a nice place to stay very central, this is definitely it. I highly recommend it!
