The apartment is everything you could expect from the reviews and even better.
Michalis and Irene's hospitality is incredible, they truly care about their guests, were always quick to respond.
The apartment itself is very stylish and spacious with two large terraces, has everything you might need during your stay. It's not too hot inside, the sun does not shine on the windows in the morning, so it's nice and cool, as well as that, there is air conditioning.
Never encountered any problems during a three night stay.
The neighborhood is rather quiet but if you are looking for something more lively, you'll find it only a few blocks away. There are cafés in 5 minutes walking distance. The metro station is very close as well, it takes maybe 20 minutes (or even less!) to get to Syntagma square (city centre) by metro, only a little longer to get to Acropoli.
Would definitely recommend staying at Michalis and Irene's place.
