Nadina's apartment is very conveniently located, with 10-15 minutes walk to the historic centre and the Acropolis. There is a 24 hour carpark literally across the street and several small restaurants/cafes just around the corner - because the area is very central but not touristy at all, i felt really local and lively and everyone was incredibly friendly and welcoming (this we found to be true EVERYWHERE we went in greece!). When we had a little snack and some drinks when we arrived late from the airport o the first night, my 11 year old daughter tried her best Greek when asking for the check - and the whole staff at the restaurant started applauding her! They were so sweet.
Nadinas apartment is very comfortable, stylishly decorated and completely quiet, despite being in a very lively area. We felt completely safe walking around with our 2 young daughters, even late at night (but everyone is out late in Greece).
Can absolutely recommend this apartment for 4 people.
