Stelios was a very nice host. He waited for us at the metro station and let us know everything we needed and also offered us to help with different things.
The studio was excelent. Better than in pictures. It was very nice, spotless clean, with everything you would need for a stay. Stelios also offered us a bottle of cold water, coffee and some snaks which was very kind from his part.
Also it is probably best located for visiting Athens. Every attraction was within walking distance. No need to use public transportation in order to get to any important spot.
I totaly recommend this accomodation.
