I stayed in Elisavet's flat for a month. The apartment was comfortable, Elisavet is a great host and I was able to work seamlessly from the apartment during weekdays. The terrace is a great size and nice for evenings with friends.
One piece of advice: ensure that you are fully comfortable with the neighborhood where the flat is located. It isn't always the most comfortable; I wouldn't recommend it to families, let's say. The flat itself, however, was wonderful.
