Nefeli's studio is in a great location - within walking distance to the tourist attractions, but far away enough so that it felt residential. She was very helpful in helping me get from the airport to her studio and was very accommodating with my late check-in, as my flight arrived at the airport at 1am. The studio itself is quite large, with a main room downstairs (which was very warm given that I visited in the winter) and a sitting room upstairs. Everything was extremely clean, which is one of my main factors when looking for accommodations abroad. I highly recommend Nefeli's studio to anybody looking to visit Athens.
