The place was just like in pictures, very clean, lots of space and many tips on what to do in Athens and around. Have used the tips and have spent one of the days on the beach, only 45min away (get the 90min metro ticket for 1.50 euro and then get a bus which is also included in price to Glyfada Beach). The hosts were very good at communicating and if we had any problems, I know I'd get a reply immediately with a solution.
The review is based on the apartment and the hosts, yes the area can seem a bit scary at first but it is very close to everything such as approx 15min walk to Plaka area and the people / shop keepers outside the apartment always say hello to you.
This being my first air bnb stay I was very happy and would recommend as the check in / out was also very easy.
