For a first-time Greece visitor, the location of the apartment, to the main attractions (Acropolis and related ruins, Plaka, and War Museum) was excellent. :-) A grocery is across the street (BAZAAR Supermarket) and paid parking is about 2-3 blocks away, but I recommend that you use the parking lot address as your destination to make navigating the maze of one-way streets easier. For those needing to get a Covid Rapid Test for your flight, you can walk 15 minutes to Lifecheck Medical Laboratories and get one for 20 euros or get one at the airport if you want to wait until the last minute (not recommended). Communication with George was good and his assistant met us at the apartment to show us the nuances of operating the clothes washer, A/C, and hot water heater.
Like any property, there are a few things that could be improved to make the Airbnb experience better. (1) The hand-held shower head in the smaller bathroom needs to be replaced, because it appears broken. (2) In the bedroom near the larger bathroom, the bed consists of a mattress on the floor. That was not a comfortable sleeping arrangement. (3) This should be an easy fix, but the bedroom and bathroom doors squeak very loudly when moved...especially noticeable when someone gets up at night to use the bathroom. Just lubricate them and that would likely do the trick.
It is easy to recommend George and his apartment for your Athens visit!
