We had such a great time in Casa Carina with my boyfriend, the place is close to Colosseo where you can start your exciting sightseeing or you can catch bus or metro to reach some destinations. We could easily find the bus shuttle to Ciampino airport it was a big help for us that it was so close to the place. There was no problem with the late check in and the croissants saved us from starving when we arrived :)
