Giannis and Aris are very friendly hosts who are always ready to help you. The flat is really tidy and cute, there is a lot of conveniences (such as washing machine, coffee machine, iron, etc.).
Athens is a city with different faces. So, all visitors should be aware of cons and pros of areas. The place is close to Monastiraki square and Acropolis, and you should learn the way to them avoiding neighborhoods that some tourists writing about. Just be positive!
Highly recommend this flat for couples!
