Staying at Evi's place was great.
Although small, the apartment has absolutely everything you need for a city visit, and the size is no issue whatsoever. The balcony however is huge, and has a view of the Acropolis, which can be enjoyed with a night cap, before turning in, or for breakfast before heading out. :)
The neighbourhood is fantastic. Great food a stones throw away (delicious gyros, and a really great family run place located here --> https://goo.gl/maps/1HxV8ia15ED2). There's a supermarket around the corner, and a pleasant 15 min stroll to Athens Central Station (Larissa).
The apartment was immaculately clean, solid wifi and AC in all the right places. Evi and her mother were extremely helpful and provided any information we needed.
We thoroughly enjoyed our stay, and would recommend it to all who are looking to visit Athens.
