Tasos's apartment is well located. You are in the Plaka on a street primarily for pedestrians, but it is not one of the main streets so you avoid the bustle.
The layout is great for a family with a teenager. To the right of the entrance is a hallway off of which are the bathroom, kitchen, and bedroom with double bed and desk. To the left of the entrance is another bedroom with two twin beds and straight in from the entrance is a family room which also can be entered from the bedroom. The kitchen is functional with a small table for two.
The apartment has 3 main drawbacks. #1 -- Like the rest of Greece, you are not supposed to flush toilet paper down the toilet so cleaning your bum with the shower next to the toilet takes getting used to if you come from a place where this is not the norm. #2 -- The ceiling of the bathroom is low and the only wall mount for the shower-head is at waist level. At 6' 4" I found the shower troublesome though not impossible to use. #3 -- Street noise in the bedroom with the twin beds. The street is generally quiet, but when people pass you can hear every word of their conversation. Ear plugs are suggested if you are a light sleeper.
