I found this hotel by reading through the tripadvisor reviews.
As stated in most reviews, the location is very convenient and the street is nice and neat. However, I realized on this trip that I prefer the other side of Via Del Corso, so if you know Roma, consider that as part of your hotel equation.
The front desk staff was exceptional, very kind and considerate. Oh so friendly and professional. They wanted to make sure that we were safe, used the security box for valuables, had an address card before venturing out, knew our location on the map, etc. We felt very well taken care of.
We were given a front room (facing street) on the second floor (203). The room was indeed small, but the bath was large, with lots of shelf space. The room and bath were very clean/fresh. On the second floor, not only did we hear ample street noise (is this the street of sirens and car alarms?), but we also had a tap dancer of sorts upstairs. Given that the rooms were small, we didn't know how one person could walk around so much. Luckily, we laughed about it.
Also, the walls must be thin, despite the age of the hotel. At night (around 10 p.m.) we heard the t.v. from the room next door (behind/above our heads).
I never thought much about a quiet location or room, but I guess I'm getting more persnickety with experience and age (especially when the dollar is weak and thus, I'm spending so much more.)
The breakfast in the sunny yellow breakfast room downstairs was fine and dandy, with cappuchino and pastries, some meats and cheeses, yogurt and fruit. Service was very efficient and everything was clean and well presented. (However, this wasn't the best breakfast I've had at a boutique hotel.)
Overall, we had a very nice stay, but still I'd go elsewhere next time because I'm interested in exploring more options in Roma. Suggestion: If the other reviews convince you that this is the place for you, ask when booking about a higher floor or a "back" room for less street noise. Also, we didn't mention any of this to management because with the heat and touring, we were too tired to repack and change rooms.
