We had a nice time in Athens and Vaitsa's apartment was a good base for exploring the city. To the Acropolis it is only a 15 min walk, to the Parliament around 20 min. The arrival from the airport was also uncomplicated, Vaitsa provided us precise information for it. The communication with Vaitsa worked fine, although we did not meet her in person. The information for getting the key were precise.
Good that the apartment has air conditioning in both sleeping rooms, it was very hot in Athens!
We could stay there comfortably with 4 adults and a child. If you are easygoing, you should make it as well. The kitchen is enough equipped for a breakfast. We did not cook neither for lunch nor dinner, so that we did not really miss anything.
All in all, a good choice for your stay in Athens!
