Nice, modern and very clean apartment. Nice decoration.
Just so that you know, there is one large bed for 2 and the second bed is actually a sofa for 2 people (which I didn't understand before arriving). It wasn't a problem and it was comfortable, just thought you might want to know.
She answered my questions (maybe not as quickly as I would have liked but it wasn't a problem). We were welcomed by the taxi driver who she sent to pick us up. I would have preferred that she welcomed us but I understand that she works. He still managed to explain us everything and was nice and helpful.
She left a couple of water bottles and bananas (that kind touch was appreciated).
Neighbourhood safe and 10-15 min walk to the touristic attractions. Restaurants are a 5min walk from there. Otherwise, taxis are very cheap in Athens (probably the cheapest taxis in Europe). Elevator, hot water and A/C available.
All in all, would recommend this appartment.
