I have to say that the offer was a good value for the price and generally you will rather be satisfied. The flat is very spacey. There is everything you need for the stay. The beds are comfortable. Eco-tips on the walls feel a little like eco-shaming. But I guess it decreases the bills. One creepy thing...there is a photo of Nestor...watching you.
The devices in a flat have attached a small user manual, however the manual of washing machine says "FOR CHECKOUT" and "Wash ONLY your towels and the bath matt. OTHING ELSE! (...)". There is provided washing powder amount and softener exactly for one wash. You might think that the machine shall not be use for your own clothes.
The neighbourhood of Omonia is decribed in guide as the worse in Athens. A lot of homeless and drug addicts nearby. However they do not seem harmful. Also there are many shops and inexpensive diners, cafes and fast foods.
The floors were icy cold for the first 2 days. Water gets warm after a minute, so be patient.
