Clean and uncluttered. Plenty of space. A much-appreciated basket of snacks were awaiting us upon arrival. The kitchen has all the appliances one could want, and plenty of nice dishes, pots and pans, etc. (It doesn't feel as if the owners were trying to outfit the apartment as minimally as possible.) Comfy beds. Lovely terrace. Nice to have the opportunity to do our laundry. Quiet as well, as most of the building houses offices, not apartments. The owners were great about responding to questions and providing us with plenty of info -- and all the guidebooks were a very thoughtful addition.
One caveat and a small suggestion. Suggestion: provide a simple translation or "graphic" for the washing machine and dryer. Our "welcoming person" DID explain it, but most of it was forgotten in the midst of arrival and a lot of additional information being offered. The German labelling did not give many hints about all the options on the dial!
The caveat is location. The apartment is in a "regular" neighborhood on a central street. So if you are wanting the convenience of being near the tourist-y neighborhoods and sites, this may not be your place. The neighborhood is fine -- perfectly safe -- and has a grocery store across the street (and also shoe stores and a bakery and banks and insurance companies and mysterious other things). But it is a schlep to get to the museums and archeological sites and more interesting areas (about 30 minute walk). Not close to Metro (which, by the way, is a great system). And we did not decipher the bus system, except for one ride. Plenty of taxis, though (but be prepared: while most Greek people seemed to speak/understand plenty of English, and even my minimal bad Greek, the taxi drivers almost universally did not). (Also, the photo o the night-lit Parthenon must have been taken through a telescope.) LOVED the rooftop terrace! Thank you for a wonderful trip!
