If you want to spend some days in Athens, go to Nick's apartment. Nick is a very good host, very kind and friendly.
Everything what says announcement is real and correct.
When I arrived he went to the train station to pick me up. The train station is close to its apartment (almost 5 block) and we walked to his apartment talking about different thing.
Then he showed me a map of the city to explain me the places that I could visit.
I recommend Nick completely and do not have badly at all to say. Everything was very well. Thank you Nick so much for everything.
Nick's apartment is very clean, very nice and it is very well located, close to Syntagma square (10 minutes walk). The neighborhood is very nice, there are some places to have coffe and to eat and there is a bakery that has tasty breads and sweets.
