Key pickup initially was unaware of the booking, delaying check-in, and they were also unaware when the keys were returned. After contacting the host the issue was resolved.
When arriving at the apartment there was a strong unpleasant smell throughout the whole place. This did not dissipate in the 3 nights we stayed there. It was also dusty, and in the bathroom there were some dead flies, which was very unusual for mid-winter.
When we left the host requested money for a cleaning fee citing that we had left the place in a disgusting state. It was claimed that we had left a horrible smell, hadn't cleaned the bathroom, stained the toilet, and hadn't put sheets on the bed. We were told that the following guests refused to stay there later that day.
The bathroom hadn't been cleaned thoroughly for a while based on the dead flies when we arrived, and the toilet needed bleaching to restain the porcelain back to white. The smell was present throughout the whole apartment, and we have no idea what was causing that. We were left instructions to put the sheets in the wash before we left, with no instructions to remake the bed. The photos we were sent afterwards show the bed in the same state as when we left showing that no one had been to check the apartment inbetween guests.
The most disappointing thing was being blamed for issues that were already present when we arrived. As we were only using the apartment to sleep in, we could put up with the smell and other issues, but it wasn't a good experience.
