This is the perfect spot for a couple wanting to explore Rome. We stayed 5 nights and never took transit. It's a bachelor and doesn't have much in the way of windows, but the location is perfect, and it's on a small lane so street noise is low (for Rome). Easy to get to via a bus from Flamingo airport (you don't have to go to Termini). It's on the ground floor so you don't have to lug your luggage. It's nicely decorated, has a very nice mosaic in the shower, there's a great use of the space that's there.
The best part though is Manuela, very attentive, quick and easy to reach if you have questions. A very solid choice for a reasonable price.
