Myself and my husband stayed in Ioanna's apartment for three nights in September. Ioanna was so attentive from our first contact and met us at Syntagma station to show us to our apartment. She took the time to show talk us through a map of the city and gave her own personal recommendations for sight-seeing, eating and drinking, which were all winners!
The apartment was super clean and had everything we needed including towels and a hairdryer.
But the most fantastic feature is the magnificent view of the Acropolis from the balcony. We didn't find a better view of it from anywhere else in the city. Priceless.
Finally, the location couldn't have been any better. It was a short 5 minute walk from Syntagma station (where you get off if coming from the airport) and a 5 minute walk again from Monastiraki station (where you get on if going to Piraeus port). All the tourist attractions and bars and restaurants are on your doorstep. We didn't need to use any public transport to get around the city.
Finally, our own personal recommendation... Try Roomie_b right next door to the apartment. Lovely staff and food.
