We've just returned from a four night stay at the Marconi Hotel in Rome and was well impressed with the interior of this 3 star establishment. The staff were very courtious and very helpful with everything and also spoke very good english.
The hotel has been recently decorated and has around 40 rooms covering the first two floors of the building.
The room itself was what you would expect of a 3 star hotel and it included tea and coffee making facilites, hairdryer, TV and a small fridge which is brill for having that bottle of wine or pint of milk. There is also a free safe deposit box in all the rooms.
The breakfast was continental buffet with ample food to set you up for the day.
There are also two excellent restaurants on the corner of the building which is great after a long tiring day walking about Rome.
All in all, a very pleasant hotel stay, and it is conveniently situated one street away from the main Termini station which is the dropoff point for most coaches from Ciampino airport.
I would most likely stay here again if returning to Rome.

Great Hotel, excellent location. Very good breakfast (meats, cheeses, cereal, eggs, juices, bakery items etc.), immaculate room and bath with a private safe in room. Would recommend this hotel to anyone.

You wouldn't want to have this as a base of operations in my opinion as the neigborhood is pretty gross and traffic and constant car horns (like 30 blowing all at the same time) are kind of annoying. We found it perfect though though to come in from Cinque Terre in the evening as the train station is a block away and grab the airport train the next am. Room was nice, clean and staff fine and the price very fair on internet . Can't comment on the breakfast as we had to leave before that. I would check out neighborhoods near the Spanish Steps for a longer stay as this train station ilke any , makes for a grimy neighborhood and you won't get the true flaver of Rome. A few years ago I stayed at a R. Steves fav "Hotel Nardizi Americano" which I thought was very nice and central and I notice he still loves it.

My friends & I stayed at the Marconi for 4 nights. Both rooms were very nice, well appointed & very clean. The breakfasts were adequate, just make sure you dont go late! The only down side in my opinion is the area. The hotel is opposite Termini rail station & whilst it is central for buses, trains etc, the area is a bit tatty with more than its fair share of beggars etc. In saying that, we never experienced any problem.
I would go back & stay in this hotel with my husband & my friends all felt the same.
All in all a very nice hotel offering good value for money.
