I booked with Konstantina and Giorgos on behalf of my mom and sister. While I did not stay here, I did visit and got a full review from my family.
Both Konstantina and Girogos were extremely communicative before and during the entire stay. They even accommodated our late night check-in. Their place was very spacious, clean, and near everything! Konstantina and Giorgos also provided several recommendations of what to see and do around Athens, and made themselves available to answer questions during the entire stay. We highly recommend staying here and would definitely book with them again!
