The stay was fine. Just a few things that one should know before renting. You have to climb many many stairs to get to the cute apartment. We had heavy luggage so that was hard because we are not young! Shower was tiny. It was hard for lager persons to shower.
The washer with soap and a celebratory bottle of champagne from the host was fantastic! Market less than a block away and great restaurant downstairs from home. Not a flat but a small apartment. Super close to metro station and Vatican. Lots of food options near.
