I think that everyone has his ideal place for a honeymoon. I think that even Moscow can turn into a romantic city, if you are in love. I recently found an interesting article www.iflyfirstclass.com/blog/first-class-deals-to-most-romantic-cities . Here are described the most popular cities on February 14. Paris didn't surprise me. I was surprised by Budapest. I never considered this city romantic. But after reading about this place more on the Internet, I realized that I was wrong. Now I am happy to go with my wife on the anniversary of the wedding in Budapest. She also doesn't suspect how beautiful and romantic the city is.
Taxi in Rome is quite contraversial. On the one hand, they have comfortable cars, you don't have to wait much because very often you can just take a car at a taxi station and the drivers know the city pretty well. But sometimes it's difficult for a foreigner to tell the driver where to go for some of them don't speak English. So, you can see all pros and cons here - rome.us/how-to-get/taxi-service.html . Take my advise - better learn some Italian before you go anywhere in this country. English is spoken in Italy but not everywhere.
