The hosts had us move between different listings, were unclear about why we were being moved, and we lost access to our luggage and the listing space for several hours while they tried to fix this.
The hosts own at least two apartments in the building. One on the fifth (top) floor (the listing we reserved), and one on the fourth. When we met with the host at checkin time to get the keys, they told us the apartment we had originally booked had had a leak, and that it needed to be repaired. We were told we could use the other apartment on the fourth. They had showed us in and gave us keys and said we had the choice of moving up to the fifth the following day.
We decided not to move up as we were only in Athens for two days and didn't want to have to repack. But on the second day, we were told that we actually had to move, as the fourth floor apartment was booked for someone else.
The hosts offered to have our luggage moved up for us once the apartment was ready. We asked to see the apartment. When the host showed us, there was other people's luggage in the apartment, and no signs of a leak.
Additionally, we were then instructed to leave the listing space as it had to be cleaned. It was raining in Athens that day, and we were forced to occupy our time outside for several hours while they prepared the fifth floor space for us.
I gave a poor rating for this because it was dishonest. We should've been told in advance of our arrival that there was some kind of mix up with regards to the reservations, rather than being lied to about why we couldn't stay in the apartment we had paid for (which was better than the one we were given temporarily for the first night).
That said, I will say that the apartment itself is nice, and the view of Zeus' temple is great.
