Konstantinos was a fantastic host: answers quickly, available, was kind enough to welcome us with our one year old and even provide us with a baby bed, a baby chair and extra gear for him. The flat is big for a studio, has everything you need (except a microwave or a hotplate but it was mentionned so no surprises). The studio was clean, comfortable and in the heart of Athens: all major sites are less then 15min walking distance and plenty restaurants just downstairs and a supermarket down the street. Thanks again K, we will definetely come back
