We stayed at the hotel in September 2010, the staff are polite and Tomas is charming, he liked to practice his English. The breakfast is buffet style and offers a selection of rolls, croissants and other breads, cheese , meats , yoghurt, cereals and drinks etc, it is served in a very nice breakfast room. The room was small but adequate with a fitted wardrobe, desk, and a double bed and night tables views over the street which when we were there was no problem with noise etc. The downside is that the hotel is in a old building with a very old metal lift, but it was working all the time with no problems whilst we were staying.
We would go back to this hotel next time we are in Rome.

We only stayed for 1 night only. Flew in to Rome relatively late traveling to Amalfi Coast first thing in the morning, hence wanted to look for accommodation close to Termini. This hotel is perfect if you have similar plans.
Rooms clean and comfy, bathroom spotless too.
Breakfast was surprisingly good after all I read about Italian preferences for the 'colazione', I mean it was the typical European what-you'd-expect but served by nice and polite staff. Wide selection of teas as well, so I'm told ;-)

The hotel is really nice. It is located on the third floor in a building with two or three other hotels. Because of this you are given a key for the door to the building, a key to the door of the hotel and a key for your room. The hotel itself is really clean and looks very modern. Maps of Roma are provided at the reception. There's even a Spark Notes of Roma there if you need it.

The rooms are also clean and modern. There are a few hundred channels on the TV, so it's impossible not to find one in your language. There's a safe. The bathroom has a big shower and comes with soap, shower cap, shampoo and skin lotion.

The only problem with the room was that the A/C didn't work the first two nights. And it wasn't because it was broken, but as we realized the third night, because they had stopped the central A/C unit from the front desk. So every night when we got back to the hotel in the 30° weather of September, we had to go to the reception and ask them to turn on the A/C.

The breakfast was pretty basic, but good. Espresso, coffee, tea, milk, juice, ham, cheese, bread, croissant, fruits, yogurt, jam, honey, cereal.

The biggest problem with our stay was that upon checking out we were asked to pay for our stay. Which would have been fine, except that it was our impression that we had paid online by credit card when we had reserved our room. It was explained to us that the credit card number we provided was merely for safety reasons or something like that.
So on the morning of our checkout, when we were supposed to be catching a train to the airport, we had to scramble to find a way to pay the hotel. We tried three different credit cards, which after 15 minute of waiting for their payment machine, were all rejected. And then we had to run out and look for an ATM to get some cash.
We did miss the train to the airport, but luckily still made the flight. Not the best way to end a vacation in Roma. So beware when you pay.

We really struggled to find an affordable home in the centre of Rome, and were really happy to find Hotel Ercoli, which was running a half price offer throughout the summer, meaning our room worked out at 75 euros a night. We thought this was a pretty good deal, and compared to other hotels, I suppose it was - but having stayed at the hotel, I'd have been very annoyed if we'd paid any more than this.

We arrived in the evening, and the person on duty at reception was an old man who was helpful enough in showing us the room, but couldn't conceal his annoyance that we couldn't converse with him in Italian. I understand his frustration, but expressing it to paying guests wasn't really the thing to do... it just made for an awkward atmosphere, and we didn't feel very welcome at all. The room was clean and comfortable, but very dark, and the air conditioner sometimes didn't seem to work.

Breakfast was ok, but there was hardly any choice of food, and we both got rather fed up of bread rolls and iced croissants after 4 days.

The hotel's saving grace was it's good location, which meant it was very easy to get to all the sights.

All in all, a very average hotel - nothing really wrong with it, but pretty poor value. The only reason I would recommend it is the fact that it was well-priced for its location.
