We needed a place to stay for one night in Athens before returning to the UK. Giannis' place was perfect.
Ground floor, so no stairs to contend with suitcases, neat and roomy.
Even when our flight from Paros was delayed, in turn delaying our check-in time, he was completely alright with it, met us and gave us the tour. He even gave us some solid reccomendations for nearby late night food and was flexible with the checkout time as our flight wasn't until four.
All in all, a great little stay.
