This place was perfect for us on our 5-night trip to Rome. It is within walking distance to everything, and a there is a close-by metro if needed (3 min walk), you can even see Vatican City when standing outside the front door. The room is gorgeous, clean and comfortable. Although there is no air conditioning, it was fine for us overnight with the window open in June. The free breakfast of toast, jam and coffee was a lovely extra and access to the kitchen was free.
The host is quick to respond to messages and very nice.
