You can not beat the location - we walked to all the classic sights. You can check out the nightlife on Campo de Fiori and Piazza Navona every night, if you wish. The stairs were not a problem except for coming and leaving with all your luggage. You even have a bakery next door for fresh bread in the morning. All arrangements were just as promised.
The one downside was predictable- it was quite noisy in the evenings. What we didn't expect was an upstairs neighbour who had the tv on very loudly both in the evenings and some mornings from 5.30. The Italian pharmacies sell very good silicone ear plugs, though..
We would absolutely recommend it. more
