Rome was definitely one of the best cities we have visited! And Valentina is one of the best hosts we have stayed with! She waited for us even though we arrived really late. Her apartment is really nice, just like the pictures!! We felt really welcome. Since we paid too much for the taxi from the airport to Valentina's B&B, she organized us a way cheaper one for our way back to the airport.
We can also recommend to get a scooter at Buzz4Tours near the Vatican to get around Rome. You don't have to walk too much and will see a lot more than taking the bus or tram!! And don't miss the catacombs at Via Appia Antica!

We will definitely come back one day and would stay at Valentina's B&B again! Thanks again for everything!
