Wow!! One of the best AirBnB places I have stayed. Literally 2 mins from Colosseum, yet on a quite cobbled street. So close to centre, and good restaurants. Super, modern apartment with private courtyard. Very clean, cold water in the fridge, coffee machine, and basically everything you could need. Welcomed by host and her brother, who were extremely helpful (as I had not pointed out we needed sofa bed), and went back home to get extra sheets/towels etc.
This place is top of my list for my next visit, highly recommended!
