My wife and i stayed in room 304 for 4 nights. The hotel is not like most as you don't have long carpeted corridoors and is set almost like an apartment block. Just like the previous review mentioned, there is no bar or restaurant but that was not a problem for us.
The room was large, high ceilings and nicely decorated, our double bed was two singles pushed together which we did not notice until after the first night - again that was not a problem. The bathroom was a decent size, although we felt the shower was a bit small. The housekeepers did a great job in keeping the room clean, there was hardly any dust.
Breakfast was continental, consisting of an option of tea, coffee, juice (i don't believe they had orange juice). crossaints, biscuits, and toast (the dry type).

There are plenty of restaurants and coffee shops next to the hotel and there's a supermarket just 10mins away. The Spanish Steps is just a 3 min walk up the road. We were able to walk everywhere (make sure you wear good shoes if you do decide to walk), the colosseum is about 20mins walking distance.

Rome is a beautiful city. We had no problems finding our way around and did not encouter any problems with pickpockets or beggers and we felt very safe walking around at night.

The Residenza Canova Tadolini is a lovely little B&B tucked away just 5 minutes walk from the Spanish steps. I travelled to Rome with my wife on our honeymoon and we spent 6 nights there. The residenza was advertised as a hotel but in fact it is more like a B&B/serviced apartments. All the rooms are beautifuuly decorated and are all different with fabric covered walls, plasma screen TV's and air con. It is unusual in that there is no bar/restaurant or even breakfast room; if you want breakfast it is delivered to your room and was of the cold continental variety with tea/coffee etc. You are sort of forced to go out for every meal as there is no option to have it in your hotel, which is good in a way. Therefore, this is not the sort of hotel where you are going to meet other travellers. Nontheless, it is in a very convenient location, 5 minutes walk from the Spanish Steps and the metro station at La Spagna and 5 minutes walk the opposite direction to Piazza del Popolo. The staff were very friendly and helpful and the room was always cleaned immaculately. There is an abundance of cafes, restaurants and wine bars nearby. Overall, this is a very pleasant, quiet place to stay in a central location.
