John is one the most caring host I've ever met.
He is super fast in answering questions or needs you might have, the apartment is curated in every details, super clean, the bed is perfect and there is also air conditioning. At my arrival there was fresh water, biers in the fridge along with food for breakfast. John was also so kind to organize a taxi transfer for me to get to his place. His apartment is just 15 minutes walk distance from Monastiraki and less then 10 minutes walk from 2 different metro station.
Needless to say that I highly recommend his place!
