The apartment had a sewage smell when we arrived on Thursday afternoon and remained the entire duration of our stay. We thought it would dissipate, so we did not complain immediately. When it did not, we messaged our host on Saturday morning. The response was that they were not aware of anything like this and would send someone over. The person did not arrive until Monday at 4:15 pm. We departed on Tuesday at 5:00 AM. When trying to resolve the situation, the host told us that this is quite normal along the river. Yet everywhere we visited in Florence - apartments of friend's along the river, shops, Hotel Lungarno along the river, restaurants, museums - none had this sewage smell. If this is normal, why is it not included in the property description? I contacted the host and over a week went by before the response came back that there was no recourse, it was just normal for this apartment. We had one of our guests that was quite sickened by the sewage smell for the entire trip. Not a great visit to Florence! We would not have rented this unit had we known. We would have looked to other AirBNB rentals. Most disappointing.
