My boyfriend and I had a lovely time in Athens and the appartment was really good. All the comments and opinions are very honest. Good location, but to get there you need to walk a quite steep hill or stairs. The appartment was very clean and tidy, the air conditioner works very well. The only thing is that we had to buy shower gel and shampoo on the first day as there was only two tiny bottles.
In overall everything was good, but our flight got delayed, arrived after midnight and had to pay 28€ extra. The communication was also good.
