Alkis' apartment was excellent. It is well located in the centre of Athens, only a few minutes walk from Metaxourghio underground station and a 15 minute walk to the main tourist areas. It was exactly as advertised - clean, well equipped and with air conditioning (which really made a difference in the August heat). Alkis himself was very helpful - he contacted me well in advance of our arrival with detailed check-in and check-out instructions, as well as instructions on how to reach the apartment from the airport, which was much appreciated. I would highly recommend his apartment if you are looking for modern, clean and good value accommodation in an excellent location for exploring Athens.
