The most important thig is that the location of the place is absolutely amazing! It's super close to the city center's attractions (near Syntagma square) so you can enjoy almost everything by foot.
Also, the apartment is in a very good condition and it's well equipped. However, two things you should know: (a) we were experiencing some issues with the WIFI, and had to contact George (the contact person on behalf of the owners) almost every day to help us fix this; And (b) One of the rooms' door and the main bathroom's door couldn't be closed properly.
Still, considering everything I would say the price is completely fair to what you get.
