Marlene's was great. She was very sweet and helpful! She gave me lots of tips on how to get around and checked in to make sure I was able to get a cab to the airport.
The place is quite cozy. I didn't know that the shower and sink would be on a different floor than the toilet but it wasn't too big if a deal.
The one thing I would say is that it doesn't feel completely private. There are curtains that cover the glass door entrances at the front and back of the unit as well as curtains covering the windows in the bedroom but they are not completely opaque...You can see silhouettes of people grabbing their bikes or throwing out their garbage every once in a while.
Other than that, I enjoyed my time in Rome at Marlene's place- Marlene was a great host.
