I had a very nice short stay in Konstantina's apartment. The place is well locatedcclose to the metro, easy to find and to navigate around the neighborhood, with a doorman in the entrance (true story) ensuring a sense of security. The building is a bit old and shows its age in a way, but otherwise is well-maintained, quite hot in winter - not to be taken for granted in Athens - and very functional overall. Konstantina is responsive, fast, discrete and polite, to my experience. Would surely recommend her place, especially if you are keen on having the authentic Athenian experience.
