The flat is perfect for 1-2 persons. I was there with my buddy and we had a great time. It is very central and so we started our tours from there. We hiked like 100+km in one week. The only thing, which can make u going nuts, is the neighbours dog. It can be pretty annoying. But it's the only negative point. I appreciated my time in Dimitris flat and he was a really nice host. And the bill was fair, too. To sum up, if u go to Athen and Dimtris flat is vailable, use it! ;)
