We booked this apartment for 9 nights but checked out with the help of Airbnb after 5 nights.
Apartment has a perfect location in the neighborhood Monti - close to nice restaurants, metro station and lots of walkable touristic highlights. So far so good.
After checking in we identified 2 main issues, (1) no warm water in main bath room and (2) awful smell at bottom floor.
Issue #1 was caused by a technical defect in heating system and required new to be ordered hardware. Unlucky!
Wrt issue #2 we initially thought to resolve the smell by opening all windows. Later we came to know it is caused by a recent leakage which needs time to dry. As the smell was disgusting we requested an alternative accommodation. As the host was not able to provide an alternative accommodation (which is safe for young kids) we asked Airbnb for a solution.
In our experience the host was reactive and did not take ownership of quickly resolving issues. This apartment should not be offered in the first place!
