This place is great for a short stay. First of all it's really close to the metro so travelling to the main areas like the acropolis was easy. It was very clean and everything we needed was there. We didn't actually meet Apostolos because we only stayed one night. We were greeted by the housekeeper who was very nice and helpful. Apostolos is also very quick to respond to messages which is another plus. He also let us keep our luggage in the apartment for the day after we checked out which was really good. Overall it was a pleasant stay.
