Williams place is in the heart of the city, 9 minutes walk uphill (quite steep) from the train station. The location is very very close to most of the city centre attractions. A 15 mins walk to the acropolis museum and 25 mins to Monastiraki.
William is a fantastic host, he use to work in the travel industry and he have very good knowledge of Athens. He also recommended me a few restaurants that were really delicious. He is friendly, open and very helpful.
The balcony is huge, you accommodate 10+ people comfortably, not that there’s so many people. The room is directly linked to the balcony so the access is great! However if you draw the blinds to get some privacy, there will not be any natural light in the room. Not a problem for me, but something to note. The view is unbelievable, unblocked view of the Parthenon, and very upfront too.
Overall fantastic experience! Could wish it to be cheaper but It is worth the price!!
