This is a charming apartment in an excellent, centralized location in Rome.
The space was very clean and the host was extremely responsive. Access was very easy, no contact needed. There are narrow, steep steps to get to the 2nd floor (which is typical) so bear that in mind with your bags.
The 4-stars accounts for the amenities. There is the bare minimum of all necessities. Exactly 2 glasses, 2 coffee cups, and 2 wine glasses. So, if you want a coffee, a juice, and a water in the morning for two of you, you’ll need to break out the wine glasses. Bath towels were simply in a plastic bag in the wardrobe. No trash bin in the bathroom. The shower drain appeared clogged, the water pooled (not enough to overflow). There was no instruction that the switch on the bathroom vanity wall turns off the water heater for the shower. So we had cold showers one day. No laundry detergent. The bedding was very poor quality and there was a duvet, but no duvet cover.
For over 120 euro per night, the amenities need to improve for a 5-star review. Otherwise, this is a perfectly lovely stay for a vacation in Rome!
