Absolutely stunning views in a really light and breezy apartment. Both beds in the main bedrooms are exceptionally comfy -- perhaps the best beds we've ever slept in!! The apartment was really clean with everything you could need (although could do with an extra saucepan or two). The layout of the apartment is really good and the location couldn't be better. We had 2 small children and didn't have to use public transport for our stay at all. The furniture inside and on the balcony is good quality and there are lots of places to unpack things.
Everything was in full working order except the lights outside on the balcony. Although we mentioned this, these were not fixed during our stay, so don't expect the full red carpet as a guest. We also had an issue with working the key to the apartment, but were always to gain access after a few attempts. Yiannis offered to help if the problem persisted -- the trick is to turn 4 times clockwise then a semi turn, pulling the door, then a little turn pushing the door.
If you're travelling with young children be aware there are a few steps outside the apartment and in the foyer. The lift is small so won't fit the biggest of buggies but did fit ours. I'd still suggest giving it a go!
Would definitely recommend to friends and family without hesitation and would definitely stay again if we returned to Athens.
