Also, the location is perfect if you need to be near Termini Station.

A good value at under 200 euros.

we stayed at the hotel for one night after a week in tuscany, and before our flight out to LAX. the hotel was clean, charming and the breakfast in the morning was great before our flight. they arranged transport to the airport - easy. we walked to the hotel from Termini (train station).
after a week in tuscany, we enjoed Guinness, fries and Black and tans at the pub across the street!

Just returned from a three night stay at the Britannia which proved a good base for exploring Rome, Plus points were good access to transport, Termini etc, convenient walking distance to many of the main attractions and friendly and helpful staff. Negatives which have all been commented on by others were the smallish size of the rooms and the cost for the facilities available. Rome is now a very expensive city and the hotel is right in the centre but nevertheless 200 Euros a night for a hotel that is no more than 3 star is a bit steep. Reception staff though were unfailingly helpful including arranging a room move for us to a higher floor with more natural light and the hotel tries hard with fish tanks in each room, plastic ducks and bamboo plants to create an individual atmosphere which mainly succeeds. We all made use of the Irish Bar on the opposite side of the road which runs a happy hour from 7-8 each evening. This reduces the price of a pint from 6 to 4.8 Euro. Handy supermarket as well at the other end of Via Napoli which has a wide range of food and drinks at reasonable prices.

I stayed at this hotel with my husband for 1 week in March 2009. We arrived very early on a sunday and were brought straight to an available room with no wait. The room was a perfect size for us, and the sound proof walls made it feel as if we were the only ones on the floor the whole week. The breakfast was perfect for our needs, and as we were usually the first ones to arrive we never had to wait for a seat. We filled up on breakfast and usually had a very light lunch in the afternoon. Staff was always courteous and provided us with everything we needed during our stay. If we stayed out late, they would leave mints on our pillows and a note of the weather forecast for the next day.

The location of the hotel was wonderful, down via viminale are at least 7 restaurants that serve high quality dinner, a gelateria, a supermarket, and a coffee bar that served fresh pizza and pasta at all hours (even on a sunday). Before our trip we utilized google maps and could view street view pictures of the location and easily navigated the area upon arrival.

Local attractions less than a few blocks away include the roman opera house (wonderful experience), national museum of rome (palazzo massimo), and the baths of diocletian. We never used a taxi or the subway during our entire trip, and utlized a hop-on hop off bus to get a tour on our way to St. Peters Square. Overall it was a wonderful week and I would stay at Hotel Britannia again.
