Stayed at the Hotel Siena over the holiday weekend 22-25 april. We booked well in advance and the hotel came very highly recommended. Arrived very late due to late arrival of Pendolino from Milan and were clearly given worst rooms in hotel. My daighter's single was ok but instead of a double bedded room we were given a minute, dark corridor-type room with two very small singles placed end to end. The room stank of cigar smoke - even the bed linen and bath towels.
When we complained we were told we could look for another hotel if we wished - this was the weekend of the new pope's installation with half a million pilgrims camping out in Rome! Breakfast was another trial we had to queue for 20 minutes for a table. What was meant to be a very special weekend was almost ruined by this disappointing hotel with very unhelpful desk staff.

Small hotel, great location near the Spanish Steps and the Via Corso. Friendly and helpful staff. Nice breakfast. Rooms are small and basic.

We loved it! We just returned from a trip to Italy spending 4 nights in Rome and 4 in Florence. Hotel Siena was perfect. The staff went out of their way to help us! My Mother is 81 and I am disabled; they kept an eye out to ensure our safety and comfort----the result was that I never wanted to leave.
The breakfast is terrific with pastries, cereals, fruits, assorted cheeses and as much coffee--any way you wish--as much as you wish!
The hotel was so central that when we asked for directions to the Spanish Steps or the Trevi Fountain, the locals smiled politely and usually said--it is just around the corner....
When I return, which cannot be too soon, this is my pick!

First of all, its location, is in the heart of Rome! next to the Spanish Steps and Fontana di Trevi (sighseeing) and Via Condotti and Via del Corso (shopping).
The staff is really friendly, breakfast is good and their capuccino is better!
The room is really clean, altough a little dark (we stayed at de 401).
I will stay here again on our next visit to Rome. And Rome... Rome is awesome!
