Great place at the heart of Kolonaki, close to stores, bars, coffee shops and restaurants, as well as the metro station. Everything was clean and comfortable, and Vivian was a perfect host, approachable and accommodating. I had to check in earlier due to unforeseen circumstances and she was quick to accommodate my change of plans and had the place ready for me to leave my luggage even though the change happened very last minute. She was also very helpful with instructions on how to check in and check out, and was kind enough to stock the fridge with coffee and cold water, as well as sugar and toilet paper (which I'm mentioning because it's often not provided in other places I've stayed at so it was much appreciated). I'd definitely stay there again during my next trip to Athens.
