Chris was very helpful and provided tips and directions to get to his place. We did not get to meet him but he communicated very well and instructions for key collection as we got in late around 2am. The apartment is such a great spot, it's very spacious and had everything we needed. Nice comfy bed, and even put out an extra single bed at our request. Location is great, very central and within walking distance to the main attractions, tram stations and Syntagma square.
