My Wife and I stayed here mid-June of 2005 - for three nights. For those confused by the same address as Casa Howard, yes, they are both in the same building. Casa Howard is on the first floor (or in North American terms, the 2nd floor) and Domina Guest House is on the second floor (or 3rd floor in NA terms)

There is a small lift suitable for only luggage - the stairs are very wide, and very easy to climb - not at all steep.

Domina Guest House has two guest rooms (that we saw). You enter a small office-like area where there is the attendant (who is mostly there during the day) We called ahead of time to confirm when we would be arriving, and he was very accomodating. (Speaks very good english for those who don't want to experiment with Italian). Rather than tell us when we could checkin, he asked when we would like to show up. This may just have been luck though - it's possible that there was nobody there the previous night, or that they had chekced out really early.

We stayed in the Room on the left side when you go in. It was done in cream colours and beiges. The bathroom is small, but really quite well finished with top-quality decoration and plumbing. (The walls are something you really have to see - finished in some kind of limestone).

There was a small couch, mostly suitable for putting your luggage on, as the room was very small - there was a small TV with about 10 channels of all-italian content. The room is air conditioned (with remote control) and worked really well. There is a small eating area with a tiny kitchenette - I wouldn't use it myself, as there are tons of really good restaurants within walking distance. The Kitchenette didn't look like it had been used in a long time.. (My wife looked it over and says it was kind of 'yucky')

There is a small window overlooking an inner walkway/alley/courtyard.. nothing to write home about or even take a picture of...

The location is pretty much unbeatable, and is mostly what you are paying for at this hotel.. 5 minutes to the Spanish Steps, 15 minutes walk to the Trevi Fountain, and amazing top-notch shopping right outside your door.
Would I stay here again? - probably not - there's too many good places and different areas of Rome to stay in - it's not that we didn't like it, we just want to try different places.

Three things we didn't like:
1. The office was right outside your door - it was a little strange to be sitting in your room, knowing someone was two feet away doing work.. not very relaxing or private.

2. The bedding coverlet had a stain on it - picky, I know, but I would expect that for the price we paid we would have had better bedding - also there was a storage area right above our bed that made me feel a bit strange.

3. When we ate breakfast the first morning, there were lots of little tiny bugs crawling around the eating area. When we brought it up with the attendant, it was corrected by the time we got back that evening - never saw them again - aparently a pidgeon had nested outside the window, and they had just gotten rid of the nest, so it may have been that..

All-in-all it was worth it if you wanted to be central to everything....
