Excellent place to stay:
1) Huge balcony with Acropolis view from the left side of the balcony, part of the balcony is separated and protected from the wind
2) Plenty of games for the kids left just below the TV
3) Nicely refurbished and has all amenities - if you wish you can cook or put food in a huge fridge
4) Very good communication with the owner
5) Very good internet speed
