The place itself was nice. It is upstairs there is an elevator (we were told it was slow and small so we didn't use it). There is a washer but be warned it doesnt dry your clothes at all. I ended up packing up my soaking wet clothes the next day after hanging them.
The apartment itself is super clean. Centrally located close to the metro and many attractions in Athens. Would reccomend the stay.
We also booked an excursion with him that let's just say was less than expected. We booked with him months in advance and he told us to pay upon arrival. We paid when we got there and he sent a "confirmation letter". We thought ok we are all set to go and thought no more about it. The morning comes we arrive early to the start point thinking we would have to check in. The time comes and nobody has arrived. We message him he saw it and didn't respond. When the bus finally arrived they actually passed us by. The lady was wicked rude and fought me about being there. Even with the confirmation. We got absolutely no instructions. Upon messaging him again he saw and chose not to respond. I suggest not booking with him if you want responses.
