Loved the place and Stamatis was a very attentive host - definitely 5 stars!
Stamatis and his brother were very friendly and helped check us in, orient us to the neighborhood and gave us some great suggestions for meals and activities. They were very responsive when we had questions about the dishwasher and they also did our laundry for us (for a nominal fee).
The loft is gorgeous and very artistically decorated, and all the appliances are modern and sleek.
The location is perfect - just a short walk to the Gazi/Technopolis area which has a ton of cool restaurants and bars/clubs. Very close to Metro as well which we used often to get around the city.
Would definitely stay here again next time we come to Athens!
