You have to carry your luggage up to the 1st floor (which is our '2nd' floor in the U.S.) then from there you can hop in a tiny freight style elevator which will take you up to the "hotel" floor(s). The entire building is not just for hotel Invictus. They are simply on one or two floors in this building. The stair case was steep and dirty and the elevator was "rikity" and very small. Once we arrived in our room, however, my wife and I were PLEASANTLY surprised. It was VERY clean, modern, and fairly quiet. I do recommend this hotel if you're okay with a good bit of walking because it isn't very close to any of the major attractions in Rome.

The initial problem was that I booked 3 nights at the Hotel RE not the Invictus. There was no Hotel RE at the correct address, this did cause a bit of a concern when we arrived, I thought we had been ripped off! After asking a local shopkeeper, we were pointed to a door to an apartment block, and rang the bell of the only hotel listed, the Invictus. It turns out this was the correct hotel as they had our booking, no explanation on the two hotel names was forthcoming.

Room was great, but aircon did not work and toilet tended to run all night when flushed. Strangest hotel ever, was actually converted apartments over several non sequential floors. Expensive for what it was at £120 per night.

There is a suberb cafe across the road on the corner, does a great breakfast of; freshly squeezed OJ, cafe latte and pastry for €3.30!

Location pretty good, easy 15 minute walk from Termini Station, 15 minutes walk from both Spanish Steps, Trevi Fountain, 10 minutes from Metro Station at Piazza Berberini.

Not sure I would stay there again

Recently refurbished, clean with all basic requirements.
Evening receptionist keen to help with directing us to sights and warning us about potential dangers in Rome.
Good location, only a 15 minute walk to Fontani di trevi, 20 mins to Piazza di Spagna.
Breakfast room is very small and was full so rather than waiting we went down to a bar opposite the hotel and had our cappucino and briosche (Italian croissant filled with jam/custard creme/chocolate) there.
We found booking with hotel cheaper than booking through other websites.
I would stay again if I was looking for a cheap 1 or 2 night stay.

The entry area was a little different, having to ring the bell everytime we wanted to get into the hotel, it was a little akward after a night out... Besides this small issue, it was a great little hotel within easy walking distance to all areas a normal visitor would want to see. A taxi ride to most areas was only about 10 euros (max).
One of the guys at reception was specially nice and cheerful, and great on advice on just about everything.
Rooms were very clean, I would definitely stay there again.
