Olivia's charming loft in Trastevere is a wonderful spot and I highly recommend it.
pros: perfect location, extremely cozy, feels quiet and private but not at all removed from the lovely neighborhood, Olivia went above and beyond to help us arrange a very comfortable car from the airport (the driver was waiting immediately outside our baggage claim with a sign) that started off our trip so well. I have never hired a driver from the airport but I think we will do this every trip from now on. She also helped us make reservations locally and was always very easy to contact.
cons: even with air condition it was a bit warm but I imagine this is true of many places, my boyfriend is 6'3" and was constantly bumping his head. he still loved the apartment but he had to walk around with his head ducked and occasionally would forget when standing up and get bonked
