We stayed for 1 week at The Navona Grande Suite, room 318, and it had everything we could have asked for. The room itself was lovely, the bed was outrageously comfortable, My wife assures me that the bath was the perfect size and shape, i'm more a shower man and the shower was great too, i'm tall but felt like there was plenty of space under the shower. Air-con was fantastic and much needed as it was extremely hot during our stay. There was plenty of space (hanging and drawers) for clothes, The TV was a decent size and positioned in a good place so you could chill out and watch a film if you wanted. Complementary Tea, coffee and hot chocolate was nice and the minibar in the room was reasonably priced too. Daily room service was good and the staff were very happy and welcoming. The hotel is situated in a good position to get to most of the main sites you would want to visit within a 20 minute walk. The Trevi fountain, The Pantheon, Colosseum, Vatican City all very accessible, but if you want a taxi, we found that downloading the FREENOW taxi app was very helpful, it used your location for collection and you put where you wanted to go and it found a taxi for you and most fares where around 16-18 euros.
I'm sure we will return to Rome again for a 3rd time in the near future and we will definitely book Navona Grande Suite again.
