Hosts were very kind and polite with us, responded very quickly into our requests, keep up the good work guys! The place is really beautifully decorated and the mezzanine floor is a really clever and nice idea :). Hot water very quickly available on the bathroom whenever you want. Great location (about 1 minute by feet from Megaro Mousikhs Metro station ) and in the center of Athens.
The sole suggestion I have for you is to have a look on the heating issue on the ground floor, I know that most of the year the weather is really good but you have to take measures for as bad days as those we stayed :)
