My wife and I stayed with two friends at the Hotel Regno for six nights. My friend booked the stay in Rome through Kirker Holidays and, after the booking was made, I did have some reservations after reading some comments on Trip Advisor - some were very good and other very poor. However Kirker are normally very good so I did look on the positive side.
The location of the hotel is excellent, there are dozens of good restaurants nearby and it was nice to join the crowds at either the Trevi Fountain or the Pantheon before turning in for the night.
We found the hotel reception staff upon arrival (Rosa and Gabrielle) both friendly and helpful. We had booked a room with a bath but the room offered only had a shower. Fortunately the hotel were able to offer us the choice of two further rooms, both with baths. The rooms were a good size with ample storage etc. Our room overlooked the Via del Corso which is a busy road but fortunately the windows were double glazed and eliminated most of the traffic noise (apart from police sirens). We were able to keep these closed at night since the room was air conditioned. Although the standard of decoration was a little tired the level of cleanliness was very good with clean towels daily and bed linen changed every other day.
As in other Trip Advisor comments the breakfast situation could be much improved. The number of tables was inadequate for the number of guests so if you arrived later that 8.00am you would search for a table (especially for more than two). The coffee was dreadful and they only seemed to provide enough fresh fruit for the first few diners. After the first day we found a really good deli down the Via delle Muratte (opposite the hotel and near the Trevi Fountain) where we brought our own bananas and took them into breakfast. However I have no complaints about the cold buffet, the cereals or croissants. If you wanted something hot it did cost extra, my wife did have a runny boiled egg one morning for 1.70 euro!!
Although there was a number for room service this was never answered. After visiting reception we did manage to get a pot of tea sent to the room after about 40 minutes.
To summarise the hotel was in a great location, it was clean and we had no major complaints – the breakfast accommodation the only thing that really let them down.

If you want to see the sights of rome well this is your hotel and location. The hotel was spotless, good size rooms, fantastic breakfast, Trevi Fountain 2 mins, Pantheon 3 mins, spanish steps 6 mins,Vatican 30 mins. can't say enough good things about this hotel.

We were initially disheartened by our room which was very small for three people. (5 Night stay) . The bathroom was tiny. The staff are very friendly and helpful. But we made the most of our stay by getting out everyday and seeing the sights of Rome. On our way back to Australia we stayed there again for our last night in Italy and we were given a larger room which we loved. I would recommend this hotel for any one with a budget.

I strongly dislike writing negative reviews, but after six nights in this hotel I felt I had no choice. After asking twice for a room for our honeymoon (on the phone and when we arrived), we were greeted by a room with two twin beds. The walls are paper thin and you can expect to be woken up very early every morning either by people walking in the hallways or by the loud construction in the dining area. After two nights, we were finally moved to another (double!) room. We were assured that they would move our luggage, but when we returned to the hotel after an hour we found the original room door propped open and the luggage still inside.

At some point, credit cards that had been stored in the room safe disappeared, and when we asked for help we were met with unhelpful staff and blank stares. Charges later appeared in another country on one of these cards before we'd even returned home! The "free wireless" offered by the hotel simply didn't work, even right next to the router. Our second hotel room also smelled of sewage every time we opened it up after being gone for a few hours. Thank goodness for windows that open!

If all you are looking for is a central location and plan to carry no valuables and sleep with earplugs in at night, then this might be the hotel for you.

The positive: Great location, very central. Excellent breakfast, attentive breakfast staff. Furnishings seemed fairly new and in good shape. Nice view over Via del Corsa if you have a room at the front of the hotel. Many restaurants nearby, short walk to Trevi Fountain and Pantheon.
