We loved our stay in Niki's loft! In person we interacted with Matina, but Niki handled most of the communications. Both of them were responsive regarding all questions and concerns and lovely to interact with. The loft is spacious, clean, comfortable, and has a great view of the Acropolis out of a window and a nice patio to relax on in the other side of the building. There is a washing machine and a drying rack to use for dirty laundry. The door has good security and a cover for the peep hole. Her apartment is the only one on its floor, so it wasn't really something we worried about, but I figured it was worth mentioning.
We loved our visit here and definitely recommend it as a great place to stay.
