Positives --
1) Location, location, location. The place is a short walk from the Colisseum.
2) On check-in day, the hosts let us leave our luggage before checking in so we could visit Rome while they were cleaning the apartment.
3) The apartment was relatively clean.
4) We contacted the host regarding the broken A/C and dusty A/C filters and he quickly sent someone to address both issues.
Negatives --
1) A/C filters were dusty.
2) One of the A/C's didn't work.
3) There were 2 small rolls of used toilet paper.
4) We had to buy soap, as we only got small gel packets to bathe on day 1.
5) There was an ironing board but no iron.
OVERALL - experience was good. The location and relative cleanliness made up for the other inconveniences.
