TLDR: if Fionnuala asks when you are checking out, save yourself the trouble and just say the check out time as stated on the listing.
For 95% of the stay, it was great. The location, the apartment itself, and the initial communication with the host was all wonderful.
There was a miscommunication with our check out time. I initially gave an ESTIMATE of when I think I would be leaving (9-9:30 in the morning, official check out time is 11), but ended up needing to stay past 9:30 because my flight was delayed. She sent a worker to come and clean the apartment at around 10:20, which caught me off guard, but I vacated the place at around 10:40, still before the official check out time. Fionnuala started claiming that I stayed past my “check out time” and ended up charging me for the time that the worker had to wait. Miscommunications happen, but the way she treated us was accusative and unprofessional. Rather than absorb a €10 charge, she chose to blame us for her mismanagement.
