Nikolaos was very responsive and easy to get a hold of. He was not there in person, but had a manager there to greet us. When the room was cold, he had someone drop off a blanket within a few hours. There was also cleaning service each day. He booked taxis to and from the airport which was very helpful (the apartment is down narrow pathways away from the street).
Unfortunately there was construction going on in the apartments above us and the noise woke us up early (before 8am) everyday, which was very unpleasant. It felt a little unfair not to mention this beforehand. However, he did refund our first night because of this and the fact we arrived a day later than planned due to airline delays.
