Konstantinos wad very reactive and had good hints.
Nice, modern and clean apartment with very good air con (small disjunction of the toilet flush - but everything ok with manual support of the mechanism).
The nice roof terrace on the 5th floor is shared (correctly described in the picture, but we overlooked it!). We could use it as we wanted and had a nice view on the acropolis.
Load neighbours in the night above us the first 2-3 days, then ok. Near a concert place, can be noisy, but was ok for us with small children.
All the basics were there (soap, repen equipment to dry and iron clothes, salt/pepper, oil/vinegar, paper towel, even cold water in the big fridge).
Good connections to M1, M3 and bus.
Near to supermarket.
