We stayed at the Aberdeen once. They were very nice but we probably won't stay there again. They gave us the smallest hotel room I have ever seen in 11 trips to Europe. I think they try to make guests feel better about it by advertising that it is the room that Rick Steves stays in when he is there.
Our friend who was traveling with us couldn't get a room at the Aberdeen and he stayed at a hotel down the street, I think it was called Hotel Paris or something like that. He had a large room and it was cheaper than the Aberdeen. He got it by calling American Express and asking them to find a hotel for him near Hotel Aberdeen. If we go back to Rome and want to stay in that area I think we are going to look into staying at the hotel where our friend stayed.
We actually enjoy staying near Termini and usually stay in that area. We find it be very convenient and have found good restaurants in that area.
