The host is very nice, he thought of everything. The apartment was very clean and beautiful (especially the terrace and it's view) and fully stacked with everything you need, we didn't have to buy anything.
The communication with the host was great, he always responded very quickly and was also very helpful.
The location is very well connected with a metro (4 minute walk away, and 4 stops from the city centre). The area is a little sketchy but we didn't have any problems regarding that.
Also the small local pizzeria (Rusticana pizzeria) was very delicious and I would recommend it to everyone that craves a late night snack.
All in all we had a great stay in Athens and a wonderful stay at the apartment.
