My partner and I stayed 4 nights in Miltos's apartment (but inadvertently only booked for 3 nights, no problems though as Miltos moved us upstairs to the very impressive Loft apartment for our extra nights accommodation).
Both apartments were perfect for us. Very clean and new, with state of the art appliances and gadgets. Everything we needed was at our fingertips, and Miltos explained the workings of the apartments in detail. Miltos also arranged a taxi pickup from the airport, and booked us a table at a lovely restaurant...nothing was too much trouble.
Restaurants, taverns, shops a mere stones throw from our apartment, and the Acropolis within easy walking distance.
I would highly recommend staying at Miltos's apartments.
