The loft is in the top floor of a building close to the center. It looks exactly as in the pictures. The interior is great. Two balconies, central heating, two ACs, Multiple TVs, great sound system, nice kitchen, everything well furnished. The flat looks safe and has a secure door. The neighbors were nice.
I never met Pantelis personally because he was on holiday, but he always promptly responded to requests, and is also reachable by phone. When you arrive you get a detailed, professional house rules / good to know guide. A cleaning lady did come once a week. She did change bed sheets and then left.
You can reach the apartment from Syntagma station or change lines and go more 2 stops with the tram.
The listing is in walking distance of the most important sightseeing spots. You can reach the parliament, Acropolis, Temple of Zeus just fine. For the rest you can buy hopon/hopoff bus or take a public transport ticket for 5 days for just 10 Euros.
There is 2 supermarkets in walking distance. Also a cinema in walking distance that has english movies with greek subtitles.
The only disadvantages I can see is that the washing machine was broken when we were there :( and that the internet connection is quite slow (5Mbit/s). Also the router crashed about every 2hours of use and needed resetting. The WiFi needs fixing!
