There is no doubt about it - this place is gorgeous. It's clean, it's central (but in a fantastic, friendly, safe neighbourhood). It's a 5 minute walk to the tram stop and one tram stop away from the very center of town. But you could walk it easily down a beautiful nearly pedestrianised avenue next to the the Zappeion. One of our absolute favorite parts of this stay was the family-owned local supermarket just about 10meters from the flat. We became such great friends with this family and they would often send us away with local greek produce and a smile.
The flat is spacious, very well equipped for any needs and all standards. We wanted for nothing. Our sheets were available to be changed and washed as often as we needed. The terrace, it goes without saying, is phenomenal. We spent much of our stay working up there and looking at the Parthenon - thinking about how lucky we were.
As might be expected in Athens, even the quieter streets can be loud. This flat was was equipped with soundproof doors and sun blocking partitions. So when everything was closed, not a single sound could be heard.
All that said, in staying for a month, one might imagine that a few issues would naturally arise. There is one particular issue that Chryssa was very concerned about and prompt at fixing. The exchange concerning this issue was a little stressful because of the nature of the issue and a few instances of misaligned communication styles.
Without going into too much detail, I will just say that Chryssa's style of managing the problem and communicating with us felt very abrupt and mildly accusatory. Unfortunately, this made us feel a bit uncomfortable. The rest of our communications with her were really nice and everyone in the other reviews seems to have had great interactions.
In sum, we had a wonderful stay. We stayed for a month and had very few issues.
