Nice place and convenient with a lot of stores around (bakery, supermarkets, cafe's etc.). Clean, and very quite during the night (which is hard to find in Athens!). Chasan was very responsive and helpful, thank you for being so helpful with our last-minute requests and adjusting to our changing schedule.
Internet was also very fast and stable, which helped a lot during the days I had to work from the apartment. The kitchen was functional, there is a stove but a bit difficult to actually cook - if that's your expectation, plus that the fridge once in a while was leaking - but that's something that can easily be fixed. If you are planning on eating out though, that shouldn't be your concern and there are plenty of options nearby.
Please have a look at the doors: the one at the bathroom didn't close properly, the one of the apartment had an external handle so it had to be locked at all times (and with 1 pair of keys that was a bit of a puzzle), and lastly the one of the building had to be locked/unlocked and sometimes got a bit stuck.
