Ioannis is the best host that I haver never had. He es very helpful and friendly. He helped us to resolve our doubts. He recommended a lot places to visit close from Athens. He is a great host. As for the apartment is a little bit small but is perfect for 3-4 persons. it is very clean and is near from the metro (100-120m). The apartmaent has A/C, important in summer time. The flat is perfect for 2-4 persons. The flat has washing machine also and this is important if you trip with a small suitcase. Definitely I recommend Ioanni's apartment because is a good place to stay a few days and, secondly, Ioannis is a great person and he will to try resolve all your doubts. I am sure. If I would to go to athens again, I would go to Ioanni's apartment, sure.
