I spent about 5 weeks at Giorgos's apartment and had a great time!
The host is very communicative (he even checked up on us a few times via messaging). There was a small welcome gift upon arrival too which was a pleasant surprise!
Something worth noting for longer stays is that there is no housekeeping. This was okay for us but definitely worth noting. Giorgos offered to find a housekeeper, but we declined after a few weeks.
The place is large enough to spread out and work for two people or more. At one point we had 4 working professionals in the apartment all taking completely different video call meetings without issue.
I mostly worked at the nice dining room table and my girlfriend at the desk in the bedroom. We only had slight issues with the wifi cutting in and out... nothing that was unavoidable.
The balconies are great and really help you get insight into the neighborhood. Although it can be a little loud at night (I worked American hours while there so it wasn't a bother) but if you're sleeping regular hours, the traffic and businesses around you might keep you up if you're a light sleeper.
The neighborhood has seen better days, but is safe and has everything you need. The grocery store is 2 minutes away, small shops directly below you, and places for local nightlife and food very nearby too! Its definitely more neighborhood and away from the tourist spots.
Speaking of tourist spots... worth mentioning you're about 40 minutes' walk to the acropolis (a walk I gladly did often during the days).
Overall really great experience here! I'd recommend the apartment for long-term stays, remote workers, and couples (and maybe a friend or two). I'd recommend it if you've seen the tourist stuff and are ready to explore more of the authentic side of Athens too!
Thanks, Giorgos for everything :) Hope to see you soon!
