Vesna's flat is an excellent base for a stay in Athens. Well-suited for a longer stay. Supermarket around the corner, a baker's right across the street and they don't sell only bread and cookies. They sell all necessities for a good breakfast, and savoury sandwiches. Good restaurants only two blocks away.
The welcome by Costas was great. There was also a welcome present. If you wish to know what? Well, book Vesna's place and find out.
