TOP NOTCH!
My wife, family friend and our four 2KG shih tzus, had a layover in Athens before Paros. We found Gianni's place last minute. He was fast responding, organized our transfers (the best transfers in Athens, from airport and to port)
The place sparkling clean, building in excellent location on maim avenue, 5 minutes from Plaka. The apartment and building from the 60's but nice and clean. The only inconvenient was that elevator had broken, but for us was fine, we were going to stay hours, and are in good shape. I do see a problem for others though. Another note for others, it is on main avenue, if you ar e alight sleeper, you will here the cars all night, and some music but not loud, just popular club in area. The only reason we know this, is that we arrived late from dinner, and woke up 3:30am.
I would stay there again in my next visit to Athens. Forgot, Giannis recommended Liondis Greek restaurant, must go.
Thank you Gianns, hopefully we will meet again
