Location - the hotel is very hard to find so if you are arriving by taxi, get the hotel to book it for you. We made the mistake of getting our own taxi (which was 10 euro more!) and spent half an hour trying to find the hotel. If you are arriving by other means, just ask anyone where the COOP is and the hotel is about 20 yards to the left. The hotel is in a great location, you can walk to anywhere in Rome and just over the bridge is Piazza Navona, lovely at night. The area is very nice and feels safe at night.
Hotel - Don't expect luxury but the hotel is nice and very clean. It is quite modern and has everything you need. There is a fridge in the room, small plasma TV and bathroom with good shower. The staff were very helpful and pleasant. My only criticism of this hotel are that the beds are not very comfortable and the pillows were awful (I think they had been washed and had gone very lumpy), the breakfast was mediocre. If the hotel paid attention to these things it would be perfect.
I would recommend this hotel mostly for it's location.

This hotel is very centrally located. You can walk to most of the major sites. This hotel is also close to 2 different bus stops. Very safe area. The room was very clean and breakfast was good. Only downside was the bed was very firm. Front desk staff was very helpful when we needed directions.

This is a very nice little hotel, beautifully located for walking to Vatican, Piazza Navona, Pantheon and other sights in Rome. It was spotlessly clean and had no unpleasant bathroom odors which we have experienced in other small hotels. Some reviewers experienced problems finding the hotel, but our taxi went right to the address which we had written out for him, and we knew, from other reviewers, to look for Scala B and ring the bell (there is no hotel sign). The staff was friendly and helpful; called the airline to confirm our departure flight. Upon arrival we found a bottle of wine chilled in the room to celebrate our anniversary.

The only down side to the hotel is the breakfast. We do not expect eggs, bacon, etc in small European hotels; however, we do expect good bread or rolls and good coffee. Breakfast consisted of sliced bread from a package, thickly sliced salami, Kraft cheese slices wrapped in cellophane, croissants, and yogurt. There was no fruit, fresh or canned. The coffee (there was a choice of "American" from a coffee pot or espresso or cappuccino from an espresso maker) was very "thin" with hardly any coffee taste--like not enough coffee grounds were used.

That said, we would stay at Roma dei Papi again; but we would buy good rolls to take to breakfast, as we did the last morning of our stay.

My mother and I stayed at the Roma dei Papi for 3 nights while visiting Rome. The rooms were impecably clean, the bathrooms were spacious and it was overall a lovely experience.

Breakfast in the morning is served in the little dining area and it's plentiful and very good. The hotel staff was incredibly nice and helpful - and although a few of them spoke very little English, it wasn't frustrating at all, they were so patient to work through the language barrier!

The only difficulty we had with this hotel was finding it! There is no signage on the building for the hotel or the address, so we were lugging our bags around for quite some time trying to find it! But, the location is wonderful, just across the street from Castel San'Angelo and about 2 blocks from St. Peter's/Vatican City.
