We'll preface that the contracted host (a contractor for the owner of this residence), provided exceptional service before and during our stay.
However, I cannot believe so many reviewers mislead others like us. Airbnb is effective b/c of honest reviews.
For serious renters in the future:
Cons:
This unit looked nothing like the pictures.
The walls are filthy
The couch is so soiled we didn't sit on it once during our 5 day stay (nor is there anywhere else clean to sit except the bed and toilet).
The showers were missing handles making it difficult to get heated water let alone a shower at all
Every drawer in the only 2 nightstands/storage areas (don't plan on unpacking your bags), were broken (we took pictures of all of them at check-in to ensure we weren't falsely accused of breaking them)
The host failed to warn us that there would also be 24/7 construction in the unit sharing walls with this one. Nonstop jack-hammering, loud men and construction starting at 7am
The amenities were bare min - 2 towels for 2 people for 5 days (including to wash/dry dishes, hair etc), a mini disposable soap (again for 2 people for 2 days)...I received better amenities and cleanliness at hostels.
This is not an rental for families, couples, germaphobes, or single female travelers
Pros:
Great neighborhood with easy access to every major site in Rome
Other than the construction in our unit, the neighborhood is very quiet
Great contractor management hosts, responsive and helpful despite the overall deplorable condition of the unit
The only thing you can't get back on holiday is time, comfort or sanity. Save all 3 by renting elsewhere.
