I would give Redi 10 stars if i could! They replied to each message within minutes, guided me via public transport from the airport to their place and waited for me outside the main door. This place was super clean, spacious, centralized (10-15 min walk to syntagma square) to the shopping area and parliament (to see changing of the guards). It is locates directly across the street from Acropolis (10min walk to main entrance side). Redi even had some food in the fridge for eating! This place is so cute and convenient and a great host to accompany it. I will definitely stay here again EVERY time i come to athens!!! Thank you Redi! :-)
