I thoroughly enjoyed my two and a half week stay at the Acropolis apartment! There was everything I needed for my visit including a washing machine and a little kitchen. It was clean and I had no issues with anything. It was very warm in Athens so I appreciated returning to the apartment with air conditioning.
You could not beat the location of the apartment, only a block away from a supermarket and 3 short blocks from the Acropolis Museum and any food or coffee you could want in Athens. It was close to many of the sights. It is in a nice quiet neighborhood and I felt safe there, and I also appreciated that it was next to a hotel so it was easy to let your friends or a taxi know how to find you. Day tours would pick up at the hotel next door so very convenient for me.
The apartment was relatively quiet. There is a little dog downstairs that would bark a few times a day for a minute or two, and there were a few conversations down the hall, but they were rare and only lasted several minutes, and they occurred only during the day. And after all, it is an apartment building, so you would expect to hear a little noise. I rather liked knowing there were people around. Oh, and the building is secure as your key lets you into the lobby, so people cannot just wander into the building.
Paris, the owner, was very accommodating with my change of time to move into the apartment. I plan to stay there again the next time I visit, and would recommend it to anyone who was going to be in Athens for longer than a few days.
