Willian is a great host and extremely helpful. He went out of way to print our boarding pass, helped us get taxis on time and with airport bus schedules. His flat is right in the center of the city. Very convenient to get to the Metro and very close to many restaurants. The room has an awesome view of the Acropolis. He was extremely flexible with our odd flight times. He was awake till 3 AM in the night and waited for to be us to be home. Excellent value and highly recommended.
