The only potential criticism I could give is that Barb downplays how wonderful her place is. It was big, roomy, spotless and in a GREAT part of Rome. When we entered the front door, we thought we might be in the wrong place as it was so nice.
I ended up staying another night in Rome at the end of our trip. Barb's place was booked so we stayed in a hotel nearby - and were soundly disappointed as it didn't come close to the experience we had at Barb's.
And Barb recommended a couple restaurants, one being La Fiaschetta which was almost next door. We were able to get a table and found it clearly the best food we had in Rome. GREAT recommendation - we didn't feel at all like we were in a touristy restaurant - we felt like a local.
Have recommended my sister stay there when she is in Rome next month, and I am always going to start with Barb's place in the future.
