I just spent a week at Deni and Geri's place, and it was perfect. The pictures and descriptions are accurate but it's hard to capture what's so great about this apartment--the location and the roof top terrace. The apartment itself isn't the Ritz, it's adequately furnished but it's not a new gleaming showplace. But for me, that was part of the attraction--I felt like I was living the way the locals do. But everything's there and works fine, including the air conditioning, which you'll need in the summer. You'll want to use the fan provided to ensure it circulates to the bedroom, the AC unit is in the living room.
But you simply cannot beat the value and the location--if you looked at a map and put a pin precisely where you'd want to live, it would come down through the living room ceiling. You're five minutes from the base of the Acropolis and literally 30 seconds from one of the most popular shopping and dining streets of the Plaka, Adrianou street. And I can't imagine a better ending to a long day than sitting on the rooftop terrace with your ouzo, olives, and feta cheese looking at the Acropolis.
So no surprises, look at the pictures, they're accurate and it's clean. But it's the location that counts.
One tip--one advantage of the location is there's a secondary entrance to the Acropolis between the apartment and the main entrance that will be mobbed by 9 am. Walk across Tripodon street to the base of the Acropolis--you'll hit a fence--turn left and walk five minutes and you're at the second, and better, entrance. If you're going to be there multiple days consider buying the 30 euro ticket the first evening you're there. The Acropolis itself is 20 euro, so for 30 euro you get another six or seven sites to be used over five days. Don't go in, just buy the ticket that first evening. Then when you go back you skip the lines and go straight through.
Also on your first evening, go the other way to Adrianou street and take little zig to the right about 10 meters to take that street and not the immediate crossing in front of you. Follow that street for 3 minutes and little grocery store will be on your right.
Fantastic place, if I go back, I'm going to Deni and Geri's place.
