My husband and I loved to stay at Miltos.
The apartment is steps away from great restaurants, it is literally inside Plaka, great shopping, restaurants, bars, bakeries, steps away. It is super quiet, no worries about noice at all.
Miltos is the best host. He gave us a great list of restaurants, activities, etc, he welcome us with a wine bottle, and let us check out late so we can enjoy the day.
The apartment has every thing you can possible need. Great comfortable space.
