Staying in Vasilios's Airbnb was fantastic and an excellent host. The apartment is well decorated and it has everything you need with lots of little extras like snacks and a computer that you can use.
It is in a good location close to lots of restaurants and nice bars and it is easy to get more central as it is very close to a bus stop.
I had an absolutely amazing time and if I return to Athens I will definitely stay here again.
