Kostas place is awesome and the location near Gazi is amazing. Tons of Restaurants to eat at right outside your door, and walkable to all key points of Athens.
My only problem was the listing made it seem like the roof top terrace was yours alone.. really it is a shared space for the entire building you are in. So keep that in mind when booking. It wasn’t a hinderance to us, but still - something guests should know.
Overall we loved the place. Very clean. Very new and modern. And you can’t beat the location. That’s what we stayed here for. Thanks Kostas and Peter for being awesome hosts!
