Very nice place in an amazing location. Koukaki Haas a lot to offer and it's very close to the centre. I loved the bathroom - jacuzzi and the luxurious shower were the highlight of the flat.
One thing to note is that the flat is very dark during the day, you need to turn on the light in the morning (for me since I'm working from home that was a big deal that's why I didn't stay longer), however for travellers or couples staying for short time and visiting Athens, this place is great.
The host was very responsive and accomodating to all my wishes.
Thank you Victor
