We loved this spot. The apartment seemed newly renovated, and was equipped with everything we needed for 5 adults. Large kitchen, comfortable beds, good water pressure, lots of hot water, and convenient to everything we wanted to see, and to places like the grocery store, wine shop, cafes, subway, cab stand. Excellent WiFi access. The balcony was lovely, but the weather was a little cold during our stay for us to use it much.
I ended up at this place because had booked a different one of Nikos' apartments, then we changed the number in our party. He accommodated all our travel changes graciously, and was very helpful.
Other people had rated his customer service skills highly, and we agree, he was great. He suggested a car to bring us from the airport into town, and arranged it for us, which went well. He also provided directions for traveling by subway for some coming in later, and they were great too.
Nikos made several restaurant recommendations; we took him up on two and were delighted with both experiences. (I think we only got into one because we said he had sent us--we hadn't made a reservation for a busy Saturday night.)
This apartment was not in any of the tourist center areas, but it was very near the Hellenic Motor museum. It was quiet at night and, as noted, near to everything we needed for convenience. The cab stand around the corner made it easy to get to restaurants, attractions etc., although we walked to some places easily.
