Grigoris' place was just wonderful. Very comfortable, clean, nicely decorated and cosy. The location is great, perfect place to discover Athens.
Grigoris is an excellent host and makes you feel welcome from start to end. Fast and clear communication. He even picked me up withe car from the metro (even though it's an easy walking distance to the flat).
So, all in all a great experience. I highly recommend Grigoris and his lovely apartment.
