The apartment is brand new and very clean. We especially liked the rooftop with its amazing view of the Acropolis.
The house is located in a quiet area without any tourists. It's located near a Hypermarket although going to the center is a bit harder. You either need to buy bus tickets from a train station to use the bus (tickets are not sold in buses) or take a taxi and pay 4-5€.
The service provided by Homm was generally very friendly. Even when we had to leave a day early, they returned the money right away and were very understanding.
Should we come to Athens again, we would book this apartment again.
