I have been working for many years in hotels industry, now managing some apartments too. My stay at this apartment was really great. It is a very very beautiful apartment, very clean with all things you might need and really good located, best place in Athens.
Great restaurants, cafés.., around, amanzing Acropolis view from the balcony, and the treatment was really great with so many tips for eating, for visiting places, for really discover the city as a local.
If you plan to visit Athens, stop looking. This is really the best option for an amazing stay, I will recommend it, knowing people will love it, in all senses :)
