This is a great place to stay next to the Acropolis. You have easy access to the metro, and you will be centrally located to many touristic attractions. For the price, the place is great! You can prepare small meals and use the kitchen, the bed is great to crash after a day out and everything is very tidy. Make sure you read the entire description accordingly, to not be surprised (eg bathroom is accessible through a corridor and steps inside the room) - I did that and Giota's description is accurate to everything, so I had zero problems. You can also use her useful guides with tips on where to eat and what to do. Giota was very flexible letting me change my check-in hour to a bit later to accommodate for my flight back home and she was quick in answering my questions.
My only recommendation for new guests is that you bring some noise-canceling protectors in case you are sensitive to sounds while sleeping. But nothing that those pharmacy protectors cannot handle. :) I definitely would stay again at Giota's place!
