This was a clean duplex apartment with a great view of the Acropolis and Hephaestus temple, walking distance to most sites.
Host was waiting for us when we arrived and there were no issues with checkin.
The view from the terrace is the reason to choose this place. It was truly amazing.
The bedrooms were spacious although the bed upstairs was pretty hard. Plenty of towels and toilet paper.
There was sufficient hot water for two showers in the morning and one bath at night, but not much more so be aware. If you turn down the heat, there risks to be no hot water so again, be aware. Kitchen had the bare basics although a pasta strainer would have been welcome. Washer and dryer worked well. The neighborhood is up and coming so be aware if coming from the Monastiraki metro in the evening. We heard the music from the avant garde theatre nearby in the bedrooms in the evening. As other reviewers have noted, it depends probably on whatever show they are performing how much you hear. During our visit we were “treated” to a pre-recorded version of the climax of Carmen Burana at 9:45 pm every night and Mozart’s Requiem at around 10:30. Quiet by 11 pm so ok for adults, maybe not so for small children.
Athens is not a quiet city: lots of motorcycles and the neighbor dog barking occasionally at night but there were no discotheques or other late night clubs that we heard from this apartment, but we were not there over the weekend.
Walking distance to nearly everything you would want to see. Overall, a decent place to stay for a few nights. I mention the above so that future travelers are prepared.
