Beautiful apartment in an amazing location. Yannis and his parents were great hosts, they live in the apartment next door and they were the easiest to reach, very helpful, communicative and hospitable.
The location is perfect! 5 minutes walk from Thissio metro station and about 10 minutes walk from the Agora and the Monasteraki square. There is also a bus stop a minute away from the apartment building. Getting around was very easy and you have everything you need close to you! The Acropolis view form the balcony is a nice bonus ;-)
The apartment is cozy and clean and offers everything you'd need. You can tell that the place is nicely renovated and well maintained. We stayed there for 5 days and had no troubles at all!
I would highly recommend this place and I would definitely stay there again next time I'm in Athens :-)
