Alexander was very helpful during our checking, we got earlier but we left our luggage with him without problems so we could walk around while the place was getting cleaned. He was very professional and good host. He communicated well and provided with details of things to do and places to go. The place is very comfortable, super clean, modern and open. It is well located, it was 5-10 min walk, close to everything from the Acropolis to dining and shopping. As a suggestion, wear comfortable shoes and be prepared to walk uphill. Take advantage of public transportation like the metro and buses, just check your times but you can save $$
