It's a lovely place, perfectly located. Lots of bars around. I would definitly recommend it for summer days where you spend most of your days outside and do not need much space.
It comes up with free coffee that you can prepare in the lovely equipped kitchenette and good restaurant choices, supermarkets and bars summed up on a handy script to take with you. The owners also have maps of the city available at your stay.
A pretty nice bar is just in front of the stay.
I can super recommend it to couples who are freshly in love or want to be super close and/or discover the city. You can't get closer to the vibes of amazing Trastevere. If you expect rainy days or need some time for yourself - lot's of bars and a yoga studio are around, too.
