I had some issues that might have been deemed just bad luck on timing, worth noting. Broken air conditioner during a very hot summer, broken toilet, leaking washer, no hot water in one shower. When I brought up one issue - owner said it wasn't his responsibility if things break down or blamed us for no hot water.
However I still give a good review bc the man in the building (Pio) who was helping the owner was so kind, put effort in trying to help and validated our concerns daily. And despite the bad luck we had - I truly thought this was an ideal rental due to its authentic Italian feel, large flat, and amazing location in the heart of Rome (everything seemed no longer than a 15 min walk). We felt like we were a part of the community by staying in this beautiful building/flat. I would stay again and hope the issues would be resolved by then!
