The apartment is even more amazing than the pictures (and the pictures are pretty amazing). It's spacious, comfortable, and beautifully decorated - and the patio area makes for a comfortable outdoor living space. There's an air conditioner in each of the two bedrooms plus another in the living room so even on hot days we were comfortable.
The immediate neighborhood has a coffee shop, 24-hour restaurant, bakery, supermarket and corner store within a two-block walk. It's also just a 15-minute walk to the Acropolis, and less than 10 minutes to a metro stop.
Soula was a spectacular host as well - she arranged to have someone meet us at the apartment early on our arrival day so that we could leave our bags in a storage room; and then was kind enough to let us to check out a couple hours later than normal so that we wouldn't have to kill time at the port waiting for our ferry to arrive.
We'd recommend Soula's place to friends and family, and look forward to staying here again on our next trip.
