Alexandros' place is just as described. Central, well equipped, well connected, clean, spacious and very close to most of Athens' main attractions. We went everywhere on foot. He is a most attentive host, replied in a matter of seconds to any of my questions. If I were to point out one thing that wasn't fully satisfactory, I could only mention the bathrooms which are a bit on the small side and don't have any shelves or wall hangers so it was a bit of a struggle to deal with beauty products and clothes ("where do I put this or that?"). But bathroom dimensions aside, I really have no complaints about anything.
