The absolute best part of this place is THE VIEW!! It's spectacular and mostly what drew me to it. There is a balcony that leads to a full rooftop as well. As an American, it is so damn cool to look out the window each moment and see one of the most well-known ancient structures of the world staring back at you! The space is clean and modern, but very small. For me as a solo traveler it was fine. The location is rather quiet at night. It's a convenient spot overall (you can walk to the Acropolis, Syntagma Square and Koukaki) but don't expect to be able run out quickly to a restaurant or convenient store. It is in the motorcycle/automotive neighborhood, so those kinds of places dominate the immediate area.
The mobile, portable wifi was very convenient and helpful, but it's a little buggy and doesn't always work right away. You have to play around with it. I wish there were also shampoo and conditioner in the shower. Make sure to bring some since it seems difficult to find a place nearby that sells them in small, flight-friendly sizes. For the price, it is an excellent deal and place to stay!
