We spent four nights here in a three bedded room. The location of the Pensione is perfect - right on Lago Argentina, it's a few minutes to Campo del Fiore for breakfast, a short walk to the Pantheon, just across the road from the Ghetto with its wonderful Roman-Jewish restaurants - ideal. Which is good, because to be honest we would not want to linger too long in the room. For two people it would be cozy, for three - ourselves and a 14 year daughter - it was cramped. The decoration - red walls with Faux-Classical decoration applied over the top - was fun, but all the nick-nacks advertised as extras - massage chair, coffee machine, trouser press - cluttered up an already limited space. We had a room facing the courtyard - still noisy from the trams out the front so we had to close the window at night, hence the need for air con. The owners could not be more friendly and helpful and their list of good, affordable restaurants in the City is worth following. For the Collisseum, book online (get the Underground tour) at the oficial site. For the Vatican Musems, the hotel offered us "skip the line" tickets but we joined the line and there wasn't a line! (this in October however). Much cheaper - or again book online. Overall - at £630 for four nights, a bit expensive for a small room, but Rome is expensive and the location is a huge plus. Oh - big tip: do not get a taxi from the main airport. Get a regular train from the airport that stops at Trastavere station (every 15 minutes, about a 25 minute ride, much cheaper than the Leonardo Express to Rome's main station). Right outside Trastavere Station, get a tram number 8 that final-stops on Lago Argentina, at the door (literally) of the Pensione. Under an hour door to door.
