The apartment was very clean and a lot more stylish than other places wed looked at. It has a big balcony which is lovely to sit on.
There was nothing we needed within the apartment that wasn't there including cute extras left my Mary and Theo e.g. mosquito repellant, some juice and some cookies which was beyond what we had expected.
Mary and Theo came out to see us on our first morning as our flight got in late the night before. They answered any questions we had about the apartment or excursions etc. And showed us features of the apartment e.g. the hot water. They were contactable throughout and arranged our taxi both to and from the airport.
The apartment has a bus stop two minutes (max) walk away which takes you straight to Athens centre - we got a five day travel pass for €9 each. There are numerous taxis around and the taxis are fairly cheap even in traffic it cost €6.60. The travel into Athens went very quick so I wouldn't let this put you off staying slightly outside of Athens. We went to the beach and to Poseidons temple all on public transport - it's cheap and very easy to navigate.
All in all, would highly recommend Mary and Theo's place, thoroughly enjoyed our time there
