We liked this hotel very much. The rooms are very basic but anyone who stays in the room and doesn't get out into the city should not stay in a hotel like this one. The breakfast in the mornings was served upstairs on the terrace and it was wonderful. All beverages (coffee tea, hot chocolate) were served with steamed milk (if requested) and that makes such a difference. We also used the terrace in the evenings to have some wine and talk with other guests.
Wifi worked well with our iPhone but only on the main floor where reception was.
This is not a place to stay if you are infirm, the hotel reception is on the 2nd floor and our room was on the 5th. There's an elevator but it is tiny and can barely fit 2 people with carry on bags. We only used it twice, while moving in and out of the hotel. The stairs don't have handrails and might pose a problem for someone who suffers from positional vertigo or who gets dizzy going down a winding road.
Our first night we ate at a hotel recommended restaurant and it was decent but we got the feeling that had we not been so hungry, we could have chosen something better on our own.
The location was fantastic. We could see the church at the top of the Spanish Steps from our windows. If you are a light sleeper, keep in mind all the rooms surround the central staircase and the lift runs up and down the center of the stairs. We were one floor below the breakfast terrace so we could hear people coming up to eat and the milk being steamed. Rather than it bothering us, we found it charming and it was an incentive to get up and eat before adventuring out.
We were able to use the computer (a Mac) provided for guests to check in for our connecting flight and look up restaurants, but describing it was a "business center" would be a stretch.
We would return, the staff were lovely and it was a good base for getting to most of the sights. We easily walked to the Pantheon, Fontana di Trevi and the Metro/subway.
