We came for 3 days in Athens with our 2 kids.
Location. That's the best part of this appartement. It's very well located. You can reach every historical site or restaurants by walking. It's very convenient.
We found the place clean but we got 2 coackroaches. Plus, the terrasse outside is full of objects like tires, old chairs, old bike etc which makes it less cosy than expected.
Talking about the terrasse, be aware that you share it with the neighbors and that people must pass in front of your door to go in their appartement. It wasn't a problème for us. They were really nice but it's good to know if you want to rent it.
One big negative point is that the AC wasn't really working. When it's 40deg outside, it makes a difference !
Wifi was ok with a limited connectivity depending on where you used it in the room.
You can have access to a very nice rooftop with a great view on the city and the acropole. It's really amazing.
To sum up: if you're looking for a place in the hearth of the city with a terrasse and if you don't not really focus on the coziness of the room. This place is for you!
