As others have mentioned, if a 5-star, highly polished, sterile and graffiti-free neighborhood is what you seek, this place is not for you. HOWEVER, if you want to be where the locals live and play, be centrally located in Athens, have a killer view of the Acropolis and are able to look past the 'creativity' of some of it's residents, then Eleni's place may be a great option. We thoroughly enjoyed our stay and would stay there again.
We arrived from Athens airport around 11pm on a Saturday night to a neighborhood swarming with people and jumping with activity. Eleni's friend 'Bea' met us at the pre-arranged meeting spot and escorted us to the apartment. As a family of four who only had 3 days in Athens at the end of a multi-week vacation, we made two decisions which - given our situation - turned out to be great choices for us:
1) We stored our large luggage at Athens airport (lower level, baggage claim, walk all the way to the left) and traveled to the apartment only with backpacks (the apartment is on the 6th floor and the elevator is TINY!). 2 large + 2 medium suitcases for 3 days = 58EUR.
2) We took a taxi from the airport (it was our first time in Greece, we do not speak the language nor did we have cell phone or data connection, and the taxi driver allowed us to call Eleni's sister Foteini, thereby allowing the driver to organize our rendezvous with Bea).
Traveling back to Athens airport was a breeze using the Metro, conveniently located 3min from the apartment.
Hop on-Hop off buses are our family's desired mode of transportation on the first day in a new city, and multiple companies are also available at Monastiraki Square - just 3min walk away.
