Opulence and Excellent Service!
During the week of Easter 2007, I stayed at the St. Regis in Rome. The service at the hotel was excellent, especially the concierge. Do not hesitate to ask the concierge to recommend restaurants and make reservations on your behalf.
I really liked the location of the hotel, which was really close to a beautiful fountain. Furthermore, the hotel was located only a 15-minute walk from the Spanish Steps, The President's Palace, and other nearby attractions.
While staying at the hotel I had a facial at spa, which was located on the top floor of the hotel. While I was there it was not difficult to book an appointment, I could gather that usually people would have no problem acquiring an appointment, if you book a couple of days beforehand. The facial and spa were really nice, but nothing special. It was just nice way to relax.
The hotel is definitely on the more expensive side, however, even if you do not stay at the hotel you should definitely have breakfast there one morning. The breakfast is American Continental, but the ambiance, service, and food is spectacular.
On a side note, I noticed a lot of people staying there were couples, and not many families with children were present.
Unique Quality: Knowledgeable concierge, spa on top floor, nicely appointed and clean rooms, delicious buffet breakfast! :)
