Aristidis was a top notch host - so accommodating, helpful, and responsive. He took amazing care of me while I had to stay in Athens for the first time for a medical trip- made sure I knew where to go, how to get there, helped with using anything, and even brought me extra cooking supplies when I needed them. His apartment was also perfectly clean and well maintained. It had what I needed for a longer term stay, and if I needed something else it was taken care of. The only reason for the 4 instead of 5 stars was the neighborhood wasn't ideal for someone visiting Athens for the first time. The good thing was the metro was very close, so easy to get elsewhere, but it's mostly residential with just the very basics. You will need to travel to get to the best restaurants, bars, sights, etc. But for my purposes this did the trick!
