We spent a night in this B&B in October 2008. We found the location superb, very close to the Trevi fountain and the bustle of central Rome. The staff were helpful, and the rooms clean.
Overall the price is good, and the location excellent.

Just come back from a weekend away in Rome having stayed at Residenza Ki for 2 nights. This Hotel itself is very hard to find since there is no sign outside so we walked past it couple of times. It is even more confusing because once you find the adress the name of the hotel does not match and the reception for residenza ki is at Fellini Inn....
The room 305 was not big, but clean apart from black hairs on the floor...that kept appearing (not ours!). The lack of bath was dissapointing, but shower was a good size and clean.
The hotel is next to a arch type car tunnel so can get a bit noisy , depending where your room is but once the telly is on you can hardly hear the outside noise and the view from the window is nice anyway.

Mom and I decided to spend a week in Rome, and picked Residenza Ki because it offered a good price in a good location.

We were disappointed on the first evening (a Saturday) because our room faced the street, and immediately below us was a restaurant that was holding an outdoor party. (I slept through it, but mom did not.) As it happens, they were going to move us to an interior room the next day anyway. We never had any problem with noise after that. In fact, the restaurant appeared to be closed during the week, and there was no party the following Saturday night.

Apart from that, we had absolutely no problems. The room was always clean. Breakfast was always good. Francesco at reception was always friendly...each morning he would draw us a map of how to get where we were going that day. The hotel is small, tucked away on a little side street... in fact you have to "just know" that you check in at the Hotel Fellini next door. But this was definitely a plus, not a minus. There was always hot water.

Lots of restaurants, bars, cafes, and so on nearby. The metro is a block away, as are main bus routes. We would usually spend our mornings walking to our destination, then take a bus back to our neighborhood in the evening, after dinner...we never had to change buses. The neighborhood felt perfectly safe at all times.

In addition to English, I heard French, German, and several other languages in the breakfast room. It was an ideal little European inn, and I would definitely stay there again.

I can only say fantastic things about this great place to stay. Firstly, a sensational location. It really is close to the Trevi as they had descibed, and in fact close to everything. One of the great pleasures of Rome is to be able to walk to as much as possible, in order to take in the street life of this buzzing city. Residenza Ki really has one of the best locations, with a very reasonable cost. The rooms are good, clean, and you feel like you're living there as it's not like a hotel. The rooms are all off a common breakfast room. They have a lovely lady who prepares breakfast for guests every morning. We found the breakfast adequate ( a typical Italian buffet, just don't expect a big American style breakfast - after all, you're in Rome ) and the staff just fantastic. Diogo at the front desk (a couple of doors down the street from the building that the Residenza is in) is particularly helpful. He is warm and generous with his advice about any questions you may have, gives GREAT suggestions for the best places to eat, and assisted us with a great many things (as did Francesco). Do not expect a "big hotel" feel, this is more like having your own little place in Rome, which is so much better. We have stayed in many places, from small B&B's to luxury 5 star, but all in all, this is great value for the very best location and friendly service in Rome. A wonderful place to stay where you will feel like a local after only a few days.
