Konstantinos's place is in the perfect location, very close to the Syntagma square and lot of food places. It can get a little loud at night, but it did not bother us. The view of the Acropolis from the bed is awesome! Konstantinos was a great host and easy to communicate. The place is new, updated and spacious. The building has an elevator which will be helpful if you have bags. I would recommend his place to anyone who visits Athens.
