Gabriel is very welcoming and accommodating to his guests. He also has great communication and is very prompt with his responses.
Our flight wasn't until later on in the evening and he allowed us to store our bags in a secure location at the apartment.
The apartment is very clean and spacious and there was ample room for all 6 guests who had a bed each. The location of the apartment is fantastic, in the centre and a 5-10 minute walk from the majority of destinations.
I would highly recommend Gabriel's apartment and would most certainly use his apartment again if I was to find myself in Athens again!
