If you are looking at this listing, do yourself a favour and book this apartment! Everything about our stay was excellent and I couldn't recommend Pelagia's apartment more highly. Our only regret was not staying for longer.
Pelagia is an extremely attentive and helpful host and has constructed an excellent guidebook of suggestions for food, drinks and sights in athens with brilliant recommendations. The apartment itself is modern, spotless and has views of the acropolis from the bed. Location is perfect, only a couple of minutes from monastiraki station to get to/ from airport and short walking distance to all major attractions. Not to mention amazing bakeries and restaurants a few blocks down the road.
As mentioned by other reviews, bring ear plugs as this area of athens can be quite noisy, but a small price to pay for an excellent stay!
