I stayed at Stelios' flat with three friends of mine for a couple of days. We all have nothing but positive remarks to make about our stay! The location was perfect - within walking distance of Monastiraki metro station, the flea market of Monastiraki, the lively bars and restaurants of Psirri and even Syntagma Square, and still, so calm and quiet!
The flat was AMAZING - the photos provided by Stelios do absolute justice to the comfortable, cozy, clean and spatious rooms! Big plus in these hot, summer days: the fact that all three areas (kitchen/living room, 2 bedrooms) were equipped with air-conditioners!
Stelios was an excellent host! He was very friendly, always available on the phone both prior to and during our stay, and he gave us nice tips about moving around the city. Our already pleasant stay became even greater thanks to Stelios' help and kind gestures (water and juice in the fridge, shampoo & shower gel in the bathroom).
On behalf of all my friends, I strongly recommend this flat to groups/families of 3 to 5 people! As all of us are Greek and may travel to Athens again soon, we will definitely pick Stelios' flat as our accommodation once again!
