Superb experience. You enter an old well kept building through massive door and go to the fourth floor by lovely old-school elevator. Suite is in fact a part of a huge apartment. Ceilings are at least 4 meters high and all the flat has that genius loci of a still living place with history. And the best of it all is lovely terrace where you can enjoy Italian sun :) Sorry that I get a bit emotional here, but I love old flats, we ourselves live in one like this :)
Being a single traveler, the room with a bathroom and terrace was perfectly suitable.
I have met three different ladies during my stay, two of them not speaking english (and I do not speak Italian :)), but I felt very welcomed, was offered a coffee when arrived and in the morning nice simple breakfast (juice, coffee and pastry)
It is cca 15 min walk to Trevi fountain, 20 min to Spanish stairs, 5 min to Barberini metro.
I definitely recommend!!!
