About

Numero 21 Luxury Guest House - Rome

Numero 21 Luxury Guest House sits on Lungotevere Prati, a quiet street along the Tiber river in Rome's Prati district. Its position makes it a practical base: the historic centre and its landmarks are within a comfortable walk, with Piazza Navona reachable in about ten minutes on foot.

The guest house is small in scale, offering a handful of rooms that lean on character — high ceilings, parquet floors, and period details. A continental breakfast with a varied spread is served each morning, and the team is known for being especially helpful, from arranging airport transfers to recommending local spots. Note that check-in is limited to a set afternoon window and pets are not accepted.
