The place is very nice itself. Has everything one needs, however it is a bit compact, the bed is actually an extendable coach, a thing to take into account. This is compensated to a degree by the very nice and wide terrace where you can chill. The building itself if not in a good shape, fortunately this is not the case with the whole floor where the flat is. Location is both good and bad, very close to the center, convenient but also in a rather poor neighborhood if this bothers you.
Overall great value for the money, all you need, convenient and cost efficient to use as a starting point to explore the whole of Athens.
