The apt: Just a described; clean and well maintained. As far as location goes, it's near Acropolis in a nice and safe residential neighborhood with nightlife options (bars, restaurants and small shops).
Constructive notes: As other have mentioned, the communication between Tia, Mike and Vaki's could be overwhelming. Getting back to back messages daily, sometimes communicating the same message redundantly could be a bit much and stressful. This is also seen in the apt. Being reminded of the house rules prior to check-in (on multiple messages), in your room, in the living room and on stickies on every cupboard and door makes you feel like you are trespassing and less like place of peace and rest. I understand the need to ensure the place is maintained, specially since the host does not live in the apt, but short and concise manual on either Airbnb or at the apt is most effective and less stressful and overwhelming for the guest.
