Grandmas house of Despoina was our lovely space for a 5 day trip with my daughters to Athens. It is located in a safe living area of Athens - 10 min. walk to the Acropolis Museum (5 min walk to Tram Direction Syngatma Place / 2 Stops), and 5 min walk to Metro).
Directly around the corner you will find a nice supermarket, and a yummy bakery where you can also get your morning coffee and tasty bread, pita etc.
On Mondays there is a farmers market where you can get delicious fresh vegetables & fruits, fish, olives, cheese an d more daily stuff to make a good meal.
The apartment reminded me a lot of the places of my greek family - lovely, clean and down to earth. No fuzz. But definitely lovely, heart warming and feel good.
If you're a fan of best gadgets, luxury stuff and rainforest showers and neon stripe lightning -> go for an other place.
If you're looking for a authentic lovely greek space and living area -> book this apartment and enjoy Athens for the time of your stay.
Despoina was very kind and helpful upfront booking and answered all my questions (are mattresses new? area safe etc.) very quick.
Besides: we slept very well in the beds (1 double in one room, 1 double + one single in the other sleeping room.
All rooms air conditioned (except kitchen - this has a balcony to sit outside and make plans for the next day).
We would definately choose this apartment again. It was kind of painful to say goodbye to the bakery staff and in the supermarket where they recognize you after the 2nd / 3rd day ...
I hope all this was helpful - enjoy your stay there :-)
