The best part is the warmheartedness of Ismini, she was very kind, friendly and helpful host.
Apartment is located in exarchia, which is a vibrant neighborhood with bars, restaurants, supermarket, metro station etc nearby. Also all the tourist attractions are in walking distance.
Apartment itself is perfect for a single traveler and maximum up to two travelers. Mainly because the place is a bit small and the bathroom is very tiny, but the big terrace makes up for it. There are two thick mattress on the floor and a bunk bed for one. There is no guaranteed electricity, and we had to call Ismini to fix it for us. Her help was nevertheless fast.
