This is a lovely place to stay! We enjoyed our time 100% and would stay here again. The host were very thoughtful and helpful. Our flight from the US arrived at 9am and they allowed us to check in early; meeting us at the apartment and helping us with our baggage and getting us settled. The apartment was very spacious and well appointed with homey little touches. The place is perfectly located with metro and train blocks away. There are museums you can walk to as well as grocery stores, bakeries and restaurants steps away. There are only two things visitors should take notice of: street is very noisy and tub/shower is really small. If you are a light sleeper you should bring earplugs (we were so tired after exploring all day it didn't really bother us) and normal sized adults will not fit in the tub!
Vicky made herself available to us to answer all our questions, had an amazing set of guide books and maps in the apartment, and even arranged a taxi to the airport for our trip back. I can not recommend this host and this apartment enough! Enjoy your stay in Athens.
