Alexis' place was comfortable, clean, and well-stocked. I had no problems at all. It is a little bit of a walk to the main tourist areas, but for me it was perfect. It is not far to the teleferique to the top of Mount Lycabettus which I did one night. Alexis sent me links to call an early morning taxi which was quite helpful. I would happily recommend Alexis' place to anyone, especially someone who wants to be in Kolonaki area.
