I would highly recommend Lorenzo's place. The location is fabulous, close to the Vatican, with a cozy cafe and pastry shop just outside the front door. The apartment itself has a lovely balcony, is super clean and chic. It was a pleasure to stay and Lorenzo was an incredibly good host. He ensured we had all we needed and added special touches. He noticed that it was my birthday when we were in Rome and left a bottle of sparkling wine for us to celebrate with.
