In the spring of 1997 I was pleasantly accomodated at Domus Pacis Residence . The rooms were very clean and extra linens were readily available, phones available in the lobby. Beautiful grounds, quiet atmosphere for relaxing after a long day in Rome. Not much to do in the immediate vicinity of the convent - but the bus stop is right outside the gates. Some think that a good way to relax from a day in the bustling city.
Some visitors report a bit of street noise bothersome.
The staff and room amenities are first rate. Room rate of Lit. Jim Catlin and spouse considered this the best experience and top value of their three week trip. Note that Janet Hubbard adds her thought that the hotel was lovely except for street noise due to heavy traffic. Also, she found the trains don't run on the weekends.
