Efthimis was probably the best host! He took care of everything, and he has complete information about what to do and where to go in Athens... his place is huge and very close to many of the must see locations. At night, we just need to walk 5 minutes down to the main road where all the restaurants and bars are around Monastiraki... during the day that same road is a flea market where you find plenty of knick-knacks...
Overall great job!
