Such a great place to stay! I would come back to Athens just to stay at George's place and enjoy the terrace for longer.
Spotlessly clean, comfortable bed, great view and amazing light.
I thought the location was perfect. Very lively, very convenient for getting everywhere. Bring earplugs if you're a light sleeper, because at the weekends there may be sound from nearby bars, but this didn't bother me at all. The area is safe, has lots of great eateries and bars, and there are supermarkets close-by too if you want to do a bit of self-catering (there is a hob, pans, kettle, fridge, coffee machines, and kitchen utensils in the flat). The shower is good, and soap, shower gel, and shampoo were provided.
I'm already missing my few days of Athenian life. George's brilliant flat played a big part in my enjoyment of the city. Highly recommended!
