The apartment is located really close to all the main sights in Athens, so we always went by foot. As it is in the middle of Athens it gets a bit loud on the evenings and through the night with all the poeple going out, but nevertheless we got a good nights sleep, so it's no big deal in our opinion. The apartment is really nicely furnished and super clean. The washing mashine and dryer are easy to use and a really big help if you're travelling for longer than two weeks! There also were a few spices, salt and pepper for cooking, a cold bottle of water in the fridge and coffee for the mornings, as well as shampoo and shower gel in the bathroom. Also the host always answered really quickly if we had any questions :) Overall we had a great time!
One thing to note though: the door to the house is really heavy and therefore hard to open. So don't worry if it doesn't open the first time you push it, you just have to push harder ^^
