Excellent place to stay, great view from the balcony with a lovely atmosphere. You'll want to stay out there all day and night!
It's a bit of a hike from the Metro especially in the heat, but it's not too bad once you know where to go. Loads of great food near the Metro station too. We got Ira to arrange a taxi from the airport and back, which was very convenient.
The AC works well, which was quite necessary in the Greek summer heat.
